Father	Owain ap Dyfnwal

Dyfnwal ab Owain (died 975) was a tenth-century King of Strathclyde. He was a son of Owain ap Dyfnwal, King of Strathclyde, and seems to have been a member of the royal dynasty of Strathclyde. At some point in the ninth- or tenth century, the Kingdom of Strathclyde expanded substantially southwards. As a result of this extension far beyond the valley of the River Clyde, the realm became known as the Kingdom of Cumbria. By 927, the kingdom seems to have reached as far south as the River Eamont.

Dyfnwal appears to have reigned between the 930s and the 970s. He is first attested in the 940s, when he is recorded associated with the ecclesiast Cathróe on the latter's journey to Continental Europe. At the midpoint of the decade, the Cumbrian kingdom was ravaged by the forces of Edmund, King of the English. Two of Dyfnwal's sons are said to have been blinded by the English, which could indicate that Dyfnwal had broken a pledge to his southern counterpart. One possibility is that he had harboured insular Scandinavian opponents of Edmund. The latter is recorded to have handed over control of the Cumbrian realm to Máel Coluim mac Domnaill, King of Alba. How much authority the Scots enjoyed over the Cumbrian realm is uncertain.

In 971, the reigning Cuilén mac Illuilb, King of Alba was slain by Rhydderch ap Dyfnwal. At some point after this act, Cuilén's eventual successor, Cináed mac Maíl Choluim, King of Alba, is recorded to have penetrated deep into Cumbrian territory, possibly as a retaliatory act. The following year, the reigning Edgar, King of the English held a remarkable assembly at Chester which numerous northern kings seem to have attended. Both Dyfnwal and his son, Máel Coluim, appear to have attended this assembly. The latter is styled King of the Cumbrians in the context of this meeting, which might indicate that Dyfnwal had previously abdicated the throne.

Dyfnwal is recorded to have died in 975 whilst undertaking a pilgrimage to Rome. Quite when he gave up the throne is unknown. One possibility is that Rhydderch had succeeded him before the killing of Cuilén. Another possibility is that the apparent retaliatory raid by Cináed marked the end of Dyfnwal's kingship. It is also possible that he held on to power until 973 or 975. In any event, Máel Coluim appears to have been succeeded by another son of Dyfnwal named Owain, who is recorded to have died in 1015. The later Owain Foel, King of Strathclyde, who is attested in 1018, may well be a grandson of Dyfnwal. Dyfnwal is likely the eponym of Dunmail Raise in England, and possibly Cardonald and Dundonald/Dundonald Castle in Scotland.

Background: the tenth century Cumbrian realm

Locations relating to the life and times of Dyfnwal.

For hundreds of years until the late ninth century, the power centre of the Kingdom of Al Clud was the fortress of Al Clud ("Rock of the Clyde"). In 870, this British stronghold was seized by Irish-based Scandinavians, after which the centre of the realm seems to have relocated further up the River Clyde, and the kingdom itself began to bear the name of the valley of the River Clyde, Ystrad Clud (Strathclyde). The kingdom's new capital may have been situated in the vicinity of Partick. and Govan which straddle the River Clyde, The realm's new hinterland appears to have encompassed the valley and the region of modern Renfrewshire, which may explain this change in terminology.

The title of Dyfnwal's son and eventual successor, Máel Coluim, as it appears on folio 9r of British Library Cotton Faustina B IX (the Chronicle of Melrose): "rex Cumbrorum".

At some point after the loss of Al Clud, the Kingdom of Strathclyde appears to have undergone a period of expansion. Although the precise chronology is uncertain, by 927 the southern frontier appears to have reached the River Eamont, close to Penrith. The catalyst for this southern extension may have been the dramatic decline of the Kingdom of Northumbria at the hands of conquering Scandinavians, and the expansion may have been facilitated by cooperation between the Britons and the insular Scandinavians in the late ninth- or early tenth century. Over time, the Kingdom of Strathclyde increasingly came to be known as the Kingdom of Cumbria reflecting its expansion far beyond the Clyde valley.

The names of Dyfnwal and his father, Owain ap Dyfnwal, as they appear on folio 25r of Oxford Bodleian Library Rawlinson B 502 (Saltair na Rann): "Domnaill meic Eogain".

Dyfnwal was a son of Owain ap Dyfnwal, King of Strathclyde. The names of the latter and of his apparent descendants suggest that they were indeed members of the royal kindred of Strathclyde. Sons of Dyfnwal seem to include Rhydderch, Máel Coluim, and Owain. The name of Dyfnwal's son Máel Coluim is Gaelic, and may be evidence of a marriage alliance between his family and the neighbouring royal Alpínid dynasty of the Scottish Kingdom of Alba. Dyfnwal's father is attested in 934. Although Dyfnwal's father may well be identical to the Cumbrian monarch recorded to have fought at the Battle of Brunanburh in 937, the sources that note this king fail to identify him by name. Dyfnwal's own reign, therefore, may have stretched from about the 930s to the 970s.

Cathróe amongst the Cumbrians

The name of Eiríkr Haraldsson as it appears on folio 36r of Oxford Bodleian Library Laud Miscellaneous 636 (the "E" version of the Anglo-Saxon Chronicle): "Yric Haroldes sunu".

Dyfnwal is attested by the tenth-century Life of St Cathróe, which appears to indicate that he was established as king by at least the 940s. According to this source, when Cathróe left the realm of Custantín mac Áeda, King of Alba at about this time, he was granted safe passage through the lands of the Cumbrians by Dyfnwal because the two men were related. Dyfnwal thereupon had Cathróe escorted through his kingdom to the frontier of the Scandinavian-controlled Northumbrian territory. The Life of St Cathróe locates this southern frontier to the civitas of Loida. One possibility is that this refers to Leeds. If correct, this could indicate that the Cumbrian realm stretched towards this settlement, and would further evince the general southward expansion of the kingdom. Another possibility is that Loida refers to Leath Ward in Cumberland, or to a settlement in the Lowther valley, not terribly far from where the River Eamont flows.

The Life of St Cathróe identifies Cathróe's parents as Fochereach and Bania. Whilst the former's name is Gaelic, the latter's name could be either Gaelic or British, and Cathróe's own name could be either Pictish or British. The fact that Cathróe is stated to have been related to Dyfnwal could indicate that the former's ancestors included a Briton who possessed a genealogical connection with the royal Cumbrian dynasty, or that Dyfnwal possessed Scottish ancestry, or else that the families of Cathróe and Dyfnwal were merely connected by way of a marriage. Cathróe is also said by the source to have been related to the wife of a certain King of York named Erich. Although the latter may be identical to Eiríkr Haraldsson—a man who is generally thought to be identical to the Norwegian dynast Eiríkr blóðøx—this man is not otherwise attested by insular sources until 947, and Northumbria itself appears to have been ruled by the Uí Ímair dynasts Amlaíb mac Gofraid and Amlaíb Cúarán during the time of Cathróe's journey. Whilst it is possible that Erich actually refers to Amlaíb mac Gofraid, if he instead refers to Eiríkr Haraldsson, it could be evidence that the latter had been based in the Solway region whilst the Uí Ímair held power in Northumbria, or that the latter indeed held power in Northumbria as early as about 946.

English aggression and Scottish overlordship

The terminology employed for Dyfnwal's realm as it appears on folio 142r of British Library Cotton Tiberius B I (the "C" version of the Anglo-Saxon Chronicle): "Cumbra land".

In 945, the "A" version of the eleventh- to thirteenth-century Annales Cambriæ, and the thirteenth- and fourteenth-century Brut y Tywysogyon reveal that the Cumbrian realm was wasted by the English. The ninth- to twelfth-century Anglo-Saxon Chronicle offers more information, and relates that Edmund I, King of the English harried across the land of the Cumbrians, and let the region to Máel Coluim mac Domnaill, King of Alba. Similarly, the twelfth-century Historia Anglorum records that the English ravaged the realm, and that Edmund commended the lands to Máel Coluim mac Domnaill who had agreed to assist him by land and sea. According to the version of events preserved by the thirteenth-century Wendover and Paris versions of Flores historiarum, Edmund was assisted in the campaign by Hywel Dda, King of Dyfed, and had two of Dyfnwal's sons blinded. If the latter claim is to be believed, it could reveal that the two princes had been English hostages before hostilities broke out, or perhaps prisoners captured in the midst of the campaign. The gruesome fate inflicted upon these sons could reveal that their father was regarded to have broken certain pledges rendered to the English. One possibility is that Dyfnwal was punished for harbouring insular Scandinavian potentates such as Amlaíb Cúarán. The latter is certainly recorded to have been driven from Northumbria by the English the year before. He could well have taken refuge amongst the Cumbrians, or may have been attempting to construct a power base in the Cumbrian periphery. The close working relationship between Edmund and Máel Coluim mac Domnaill suggests that Amlaíb Cúarán was unlikely to have been harboured by the Scots during this period. Edmund's strike upon Dyfnwal's realm, therefore, seems to have been undertaken as a means to break a Cumbrian-Scandinavian alliance, and to limit the threat of an insular Scandinavian counter offensive from the Forth-Clyde region. The southward expansion of the Cumbrian realm—an extension possibly enabled by the insular Scandinavian power—may have also factored into the invasion, with the English clawing back lost territories. Whatever lay behind the campaign, it is possible that it was utilised by the English Cerdicing dynasty as a way to overawe and intimidate neighbouring potentates.

The Giant's Grave, a collection of apparent tenth-century monuments at Penrith. The stones display significant Scandinavian influences, and are traditionally associated with a legendary king, variably known as Owain Caesarius. It is possible that this figure refers to Dyfnwal's father or son.

Although the Wendover version of Flores historiarum alleges that Máel Coluim mac Domnaill was given Cumbrian territory to hold as a fief from the English, the terminology employed by the more reliable Anglo-Saxon Chronicle seems to suggest that Edmund merely surrendered or granted the region to him, or that he merely recognised certain rights of the Scots in the region (such as the right to tribute). Edmund, therefore, may have allowed his Scottish counterpart to collect tribute from the Cumbrians in return for keeping them in check and for lending Edmund military assistance. It is possible that the territory in question corresponds to the region around Carlisle—roughly modern-day Cumberland—which in turn could reveal that the Scots were already in possession of the kingdom's more northerly lands. It is conceivable that the Scots were allowed authority over Cumbrian territory because it was too far to be overseen effectively by the English themselves. As such, it may have been recognised that the Cumbrian territories were situated within the Alpínid sphere of influence rather than that of the Cerdicings. In any event, it is uncertain what authority Máel Coluim mac Domnaill enjoyed over the Cumbrians. Although it is possible that there was a temporary Scottish takeover of the realm, Dyfnwal lived on for decades, and there were certainly later kings. In fact, the Wendover version of the Flores historiarum reveals that the Cumbrians were ruled by a king the year after Edmund's invasion. The concord between the English and the Scots could have been precipitated by the former as a way of further securing their northern frontier from the threat of insular Scandinavians. Similarly, the English campaign against the Cumbrians may have been undertaken in order to isolate the Scots from an alliance with the Scandinavians. In this way, Edmund's conquest and grant of Cumbrian territories to his Scottish counterpart may have been a way of winning the latter's obeisance.

The terminology used to denote an alliance of Scots, Cumbrians, and Englishmen, on folio 32r of Oxford Bodleian Library Rawlinson B 489 (the Annals of Ulster).

Edmund was assassinated in 946, and succeeded by his brother Eadred, a monarch who soon after made a show of force against opposition in Northumbria, and received a renewal of oaths from his Scottish counterpart. In about 949/950, Máel Coluim mac Domnaill is recorded to have raided into Northumbria, perhaps against the retrenched forces of Eadred's Scandinavian opponents. Whilst it is possible that this event was undertaken in the context of compensation for the English campaigning against the Cumbrians in 946, an alternate possibility is that this Scottish invasion was instead an opportunistic attempt to extract tribute from the Northumbrian ruler Osulf (fl. 946–950), rather than the York-based Scandinavians.

In 952, the seventeenth-century Annals of the Four Masters and the fifteenth- to sixteenth-century Annals of Ulster appear to report an attack upon the Scandinavians of Northumbria by an alliance of English, Scots, and Cumbrians. If these two annal-entries indeed refer to Cumbrians rather than Welshmen, it would appear to indicate that the former—presumably led by Dyfnwal himself—were supporting the cause of the English with the Scots. One possibility is that the annal-entries record the clash of this coalition against the forces of Eiríkr, a man who was finally overwhelmed and slain two years later.

Dyfnwal's name as it appears on folio 59r of Oxford Jesus College 111 (the Red Book of Hergest): "dỽnwaỻaỽn".

There is also reason to suspect that a man other than Dyfnwal ruled as king in the wake of Edmund's 945 campaign. For instance, a certain Cadmon is recorded to have witnessed two royal charters of Edmund's successor, Eadred—one in 946 and another in 949—which could be evidence that Cadmon was then the ruling Cumbrian monarch. There may be evidence indicating that, from about the time of the campaign until at least 958, the English regarded the land of the Cumbrians as part of the English realm. For instance, a charter apparently issued upon Eadred's coronation—the first of the two witnessed by Cadmon—accords Eadred the title "king of the Anglo-Saxons, Northumbrians, pagans, and Britons", whilst a 958 charter of Eadred's royal successor Edgar accords the latter kingship over "the Mercians, Northumbrians and Britons". The fact that the acta of Edmund, Eadred, and Edgar fail to record the presence of Dyfnwal could be evidence of English rule over the Cumbrians, who may have been in turn administered by English-aligned agents.

Cumbrian and Scottish contention

The name of Illulb mac Custantín as it appears on 29v of Paris Bibliothèque Nationale Latin 4126 (the Poppleton manuscript): "Indolf filius Constantini".

Máel Coluim mac Domnaill was slain in 954, and succeeded by Illulb mac Custantín. At some point during the latter's reign, the Scots permanently acquired Edinburgh from the English, as partly evidenced by the ninth- to twelfth-century Chronicle of the Kings of Alba. Confirmation of this conquest seems to be preserved by the twelfth-century Historia regum Anglorum, a source which states that, during the reign of Edgar, King of the English, the Northumbrian frontier extended as far as the Tinæ, a waterway which seems to refer to the River Tyne in Lothian. The acquisition of Edinburgh, and extension into Lothian itself, may well have taken place during the reign of the embattled and unpopular Eadwig, King of the English. Illulb's attack may be evidenced by passages preserved by the twelfth-century Prophecy of Berchán which not only note "woe" inflicted upon the Britons and English, but also the conquest of foreign territories by way of Scottish military might. The notice of Britons in this text could be evidence that Illulb campaigned against Cumbrian-controlled territories. Such conflict may have meant that the apparent Cumbrian extension southwards was mirrored by movement eastwards. One possibility is that the Scots seized Edinburgh not from the English but from Cumbrians who had temporarily taken possession of it. Certainly, the fortress of Edinburgh had anciently been a British stronghold.

Rhydderch, son of Dyfnwal

The name of Rhydderch ap Dyfnwal, as it appears on folio 8v of British Library Cotton Faustina B IX: "Radhardus".

After Illulb's death in 962, the Scottish kingship appears to have been taken up by Dub mac Maíl Choluim, a man who was in turn replaced by Illulb's son, Cuilén. The latter's death at the hands of Britons in 971 is recorded by several sources. Some of these sources place his death in locations that could refer to either Abington in South Lanarkshire, Lothian, or the Lennox. There is reason to suspect that Cuilén's killer was a son of Dyfnwal himself. The Chronicle of the Kings of Alba reports that the killer was a certain Rhydderch ap Dyfnwal, a man who slew Cuilén for the sake of his own daughter. .....

The name of Cuilén mac Illuilb as it appears on folio 29v of Paris Bibliothèque Nationale Latin 4126: "Culen filius Indulf".

Although there is no specific evidence that Rhydderch was himself a king, the fact that Cuilén was involved with his daughter, coupled with the fact that his warband was evidently strong enough to overcome that of Cuilén, suggests that Rhydderch must have been a man of eminent standing. According to the Prophecy of Berchán, Cuilén met his end whilst "seeking a foreign land", which could indicate that he was attempting to lift taxes from the Cumbrians. Another way in which Cuilén may have met his end concerns the record of his father's seizure of Edinburgh. The fact that this conquest would have likely included at least part of Lothian, coupled with the evidence placing Cuilén's demise in the same area, could indicate that Cuilén was slain in the midst of exercising overlordship of this contested territory. If so, the records that link Rhydderch with the regicide could reveal that this wronged father exploited Cuilén's vulnerable position in the region, and that Rhydderch seized the chance to avenge his daughter.

The name of Cuilén's apparent successor, Cináed mac Maíl Choluim, as it appears on folio 15r of Oxford Bodleian Library Rawlinson B 488: "Cinaeth mac Mail Cholaim". Cináed is recorded to have overseen an invasion of Cumbria during his reign.

Cuilén seems to have been succeeded by his kinsman Cináed mac Maíl Choluim. One of the latter's first acts as King of Alba was evidently an invasion of the kingdom of the Cumbrians. This campaign could well have been a retaliatory response to Cuilén's killing, carried out in the context of crushing a British affront to Scottish authority. In any event, Cináed's invasion ended in defeat, a fact which coupled with Cuilén's killing reveals that the Cumbrian realm was indeed a power to be reckoned with. Whilst it is conceivable that Rhydderch could have succeeded Dyfnwal by the time of Cuilén's fall, another possibility is that Dyfnwal was still the king, and that Cináed's strike into Cumbrian territory was the last conflict of Dyfnwal's reign. In fact, it could have been at about this point when Máel Coluim took up the kingship. According to the Chronicle of the Kings of Alba, Cináed constructed some sort of fortification on the River Forth, perhaps the strategically located Fords of Frew near Stirling. One possibility is that this engineering project was undertaken in the context of limiting Cumbrian incursions.

Amongst an assembly of kings

Dyfnwal's name as it appears on folio 9r of British Library Cotton Faustina B IX: "Dufnal".

There is evidence to suggest that Dyfnwal was amongst the assembled kings who are recorded to have met with Edgar at Chester in 973. According to the "D", "E", and "F" versions of the Anglo-Saxon Chronicle, after having been consecrated king that year, this English monarch assembled a massive naval force and met with six kings at Chester. By the tenth century, the number of kings who met with him was alleged to have been eight, as evidenced by the tenth-century Life of St Swithun. By the twelfth century, the eight kings began to be named and were alleged to have rowed Edgar down the River Dee, as evidenced by sources such as the twelfth-century texts Chronicon ex chronicis, Gesta regum Anglorum, and De primo Saxonum adventu, as well as the thirteenth-century Chronica majora, and both the Wendover and Paris versions of Flores historiarum. One of the names in all these sources—specifically identified as a Welsh king by Gesta regum Anglorum, Chronica majora, and both versions of Flores historiarum—appears to refer to Dyfnwal. Another named figure, styled King of the Cumbrians, seems to be identical to his son, Máel Coluim.

An early twentieth-century depiction of Edgar being rowed down the River Dee by eight kings. According to the Anglo-Saxon Chronicle, Edgar met six kings at Chester. By the twelfth century, chroniclers alleged that eight kings rowed Edgar down the river in an act of submission. One of these eight was Dyfnwal himself.

Whilst the symbolic tale of the men rowing Edgar down the river may be an unhistorical embellishment, most of the names accorded to the eight kings can be associated with contemporary rulers, suggesting that some of these men may have taken part in a concord with him. Although the latter accounts allege that the kings submitted to Edgar, the Anglo-Saxon Chronicle merely states that they came to an agreement of cooperation with him, and thus became his efen-wyrhtan ("co-workers", "even-workers", "fellow-workers"). One possibility is that the assembly somehow relates to Edmund's attested incursion into Cumbria in 945. According to the same source, when Edmund let Cumbria to Máel Coluim mac Domnaill, he had done so on the condition that the latter would be his mid-wyrhta ("co-worker", "even-worker", "fellow-worker", "together-wright"). Less reliable non-contemporary sources such as De primo Saxonum adventu, both the Wendover and Paris versions of Flores historiarum, and Chronica majora allege that Edgar granted Lothian to Cináed in 975. If this supposed grant formed a part of the episode at Chester, it along with the concord of 945 could indicate that the assembly of 975 was not a submission as such, but more of a conference concerning mutual cooperation along the English borderlands. The location of the assembly of 973 at Chester would have been a logical neutral site for all parties.

The name of Edgar as it appears on folio 142v of British Library Cotton Tiberius B I (the "C" version of the Anglo-Saxon Chronicle): "Eadgar Angla cing".

One of the other named kings was Cináed. Considering the fact that the Anglo-Saxon Chronicle numbers the kings at six, if Cináed was indeed present, it is unlikely that his rival, Cuilén's brother Amlaíb mac Illuilb, was also in attendance. Although the chronology concerning the reigns of Cináed and Amlaíb mac Illuilb is uncertain—with Amlaíb mac Illuilb perhaps reigning from 971/976–977 and Cináed from 971/977–995—the part played by the King of Alba at the assembly could well have concerned the frontier of his realm. One of the other named kings seems to have been Maccus mac Arailt, whilst another could have been this man's brother, Gofraid. These two Islesmen may have been regarded a threats by the Scots and Cumbrians. Maccus and Gofraid are recorded to have devastated Anglesey at the beginning of the decade, which could indicate that Edgar's assembly was undertaken as a means to counter the menace posed by these energetic insular Scandinavians. In fact, there is evidence to suggest that, as a consequence of the assembly at Chester, the brothers may have turned their attention from the British mainland westwards towards Ireland.

The name of Thored Gunnerson as it appears on folio 58v of British Library Cotton Domitian A VIII (the "F" version of the Anglo-Saxon Chronicle): "Thored filius Gunnerses".

Another aspect of the assembly may have concerned the remarkable rising power of Amlaíb Cúarán in Ireland. Edgar may have wished to not only rein in men such as Maccus and Gofraid, but prevent them—and the Scots and Cumbrians—from affiliating themselves with Amlaíb Cúarán, and recognising the latter's authority in the Irish Sea region. Another factor concerning Edgar, and his Scottish and Cumbrian counterparts, may have been the stability of the northern English frontier. For example, a certain Thored Gunnerson is recorded to have ravaged Westmorland in 966, an action that may have been undertaken by the English in the context of a response to Cumbrian southward expansion. Although the Scottish invasion of Cumbrian and English territory unleashed after Cináed's inauguration could have been intended to tackle Cumbrian opposition, another possibility is that the campaign may have been executed as a way to counter any occupation of Cumbrian territories by Thored.

Death and descendants

Dyfnwal's title as it appears on folio 33v of Oxford Bodleian Library Rawlinson B 489. Irish sources accord him the title rí Bretan ("King of the Britons").

Both Dyfnwal and his English counterpart died in 975. According to various Irish annals, which style Dyfnwal King of the Britons, he met his end whilst undertaking a pilgrimage. These sources are corroborated by Welsh texts such as the thirteenth- and fourteenth-century Brenhinedd y Saesson, and Brut y Tywysogyon, with the latter stating that Dyfnwal died in Rome having received the tonsure. Such religious retirement late in the life of a ruler was not uncommon amongst contemporaries. For example, Custantín evidently became a monk upon his own abdication, whilst Amlaíb Cúarán retired to the holy island of Iona in pilgrimage. One possibility is that Dyfnwal decided to undertake his religious journey—or was perhaps forced to undertake it—as a result of the violent actions of Rhydderch.

The title of Dyfnwal's son, Máel Coluim, as it appears on folio 15v of Oxford Bodleian Library Rawlinson B 488: "rí Bretan Tuaisceirt" ("king of the Britons of the north").

It is conceivable that Dyfnwal was still reigning in 973, and that it was Edgar's death two years later that precipitated the transfer of the kingship to Dyfnwal's son Máel Coluim, and contributed to Dyfnwal's pilgrimage to Rome. In fact, the upheaval caused by the absence of the English and Cumbrian kings could well have contributed to Cináed's final elimination of Amlaíb mac Illuilb in 997. Another possibility is that Máel Coluim's part in the 973 assembly may have partly concerned his father's impending pilgrimage, and that he sought surety for Dyfnwal's safe passage through Edgar's realm. The fact that Máel Coluim is identified as one of the assembled kings could indicate that Dyfnwal had relinquished control to him at some point before the convention. Evidence that he had indeed assumed the kingship may exist in the record of a certain Malcolm dux who witnessed an English royal charter in 970. Although the authenticity of this document is questionable, the attested Malcolm could well be identical to Máel Coluim himself. If Máel Coluim was indeed king in 973, Dyfnwal's role at the assembly may have been that of an 'elder statesman' of sorts—possibly serving as an adviser or mentor—especially considering his decades of experience in international affairs. The fact that he left his realm for Rome could be evidence that he did not regard his realm or dynasty to be threatened during his absence.

The name of Dyfnwal's apparent son, Owain, as it appears on folio 60r of Oxford Jesus College 111: "owein". This source records the latter's death in 1015.

Surviving sources fail to note the Cumbrian kingdom between the obituaries of Dyfnwal in 975 and his son, Máel Coluim, in 997. There is reason to suspect that Dyfnwal had another son, Owain, who reigned after Máel Coluim. For instance, according to the "B" version of Annales Cambriæ, a certain Owain—identified as the son of a man named Dyfnwal—was slain in 1015. This obituary is corroborated by Brut y Tywysogyon, and Brenhinedd y Saesson. Although it may be possible that the record of this man's death refers to Owain Foel, King of Strathclyde, there is no reason to disregard the obituaries as erroneous. If the like-named men are indeed different people, they could well have been closely related. Whilst the former may have been a son of Dyfnwal himself, the latter could well have been a son of Dyfnwal's son, Máel Coluim. The Owain who died in 1015, therefore, would seem to have assumed the Cumbrian kingship after Máel Coluim's death in 997, and would appear to have reigned into the early eleventh century before Owain Foel's assumption of the throne.

The cairn of Dunmail Raise lying between the dual carriageways of the A591 road.

Dyfnwal may be the man immortalised in the name of a mountain pass in the Lake District known as Dunmail Raise (meaning "Dyfnwal's Cairn"). According to popular legend, a local king named Dunmail was slain by Saxons on the pass and buried beneath a cairn. Forms of this tradition may date to about the sixteenth century, as the place name is first marked on a map dating to 1576. By the end of the seventeenth century, it was claimed that the place name marked the site of "a great heap of Stones call'd Dunmail-Raise-Stones, suppos'd to have been cast up by Dunmail K. of Cumberland for the Bounds of his Kingdom". Forms of the tale began to appear in print in the following century. In time, the ever-evolving legend became associated with the events of 945. The cairn itself lies between the dual carriageways of the A591 road. It seems to have marked an old boundary between Westmorland and Cumberland, and might have also marked the southern territorial extent of the Cumbrian kingdom. Nevertheless, the site's alleged importance in the early mediaeval period cannot be proven. Other place names that may be named after Dyfnwal include Cardonald (grid reference NS5364), and Dundonald/Dundonald Castle (grid reference NS3636034517).
