Dyddgu (Duddgu) ferch Robert

coheir of Meredith.

Also known as Jane ferch Robert, born Cedewain, Montgomeryshire, Wales.


In about 1197 Dyddgu married Meilir "Gryg" ap Gruffudd.

Dyddgu was the grandaughter of Owen Gwynedd Fawr [=The Great], Prince of Gwynedd r.1137-70], who was the younger brother of Cadwaladr (Cadwalader). Hughes states she was the great grandaughter of Llywarch ap Trahaern [570], who I show as the father of Gwladys, 1st wife of Owain with Dyddgu descending from an unknown mistress of Owain

This fits with the comment by Rowley-Morris that a Blayney married an heiress "of the house of Owen Gwynedd" pg68 [35], and with the fact that John Blayney of Gregynog included the arms of Owen Gwynedd in his 1636 panelling [50] & [55].

There is a claim that the descent of the "noble" family of Blayney "Is from the ancient kings of Britain, in a direct line from Cadwallader, a younger son of the Prince of Wales" [326]. I have looked to see if this claim relates to Cadwaladr ap Gruffydd who married Alice de Clare (dau of Richard FitzGilbert de Clare descended from Norman Lords). All my research reveals that the Blayneys descended from his brother, Owain Gwynedd (Prince of Gwynedd) and not this Cadwaladr. The good news is that this Cadwalader/Cadwaladr doesn't appear to be an ancestor one could be proud of. See Cad

A side note on Cadwallader: Cadwall, 2nd son of Griffith (Gruffydd ap Cynan) had Richard (hicert) by Alice de CLARE who married Agnes ferch Rarwedd and in turn were the parents of Adlais (Alice). Adlais first married Ithel Fychan ab Ithel LLOYS and had Angharad ferch Ithel (wife of Tudor H�n ap Goronwy) and secondly, she married Sir Tudor (Tudur) ab Ednyfed Vychan the ancestors of the royal Tudor line.

However, we are able to show that the Cadwallader claimed as an ancestor of the Blayneys was most likely St Cadwaladr Fendigaid ap Cadwallon (Cadwaladr the Blessed (c603-664), King of Gwynedd, although not in a pure patrilineal descent as it does involve some female lines. This is supported by Kevin McKenzie [145]. See the descent to Dyddgu who married Meilir "Gryg" (ancestors of the Blayneys).

    Many genealogies have Sitric I the son of Halfdon's brother Ivar the Boneless
    which would still have him descended from Ragnar, but why is he Halfdansson?
    [perhaps Halfdan helped his "boneless" brother sire a son!!]

       inherited his position. Olaf was the son of Sigtrygg by a previous marriage, but the
       Northumbrians accepted him, and his uncle Guthfrith served as regent."

From here there are two alternative genealogies: Edwin had Ealdgyth ferch Edwin who m. 1st Goronwy then Uchtred of Atiscross who had Edwin (Edwyn,Eadwine) of Tegeingl (Lord of FLINT). The alternative line is from Leofric who m. Godgifu (Lady Godiva) and had Aelgar (Aelfgar) of Mercia who m.

John Donne

John DONNE b.1572; d.1631 (poet) claimed ancestry with Dwn family of Kidwelly with their arms on a 1591 portrait namely a coat of arms of "azure, a wolf salient", with a crest of a quiver full of snakes. On taking holy Orders he stated "A sheaf of snakes used heretofore to be my seal, the crest of my poor family". His new seal was "The cross (my seal at baptism) spread below, Does by that form into an anchor grow." [625]

Other evidence points to John Donne being a companion and probably a close cousin to Lewis Dwn [145]

Helped brother Owain rule until he was exiled in 1144 for "misconduct". In 1143 his men killed Anarawd ap Gruffudd, Prince of Deheubarth (and betrothed of Owain's daughter) in a land dispute. Warrington's "History" has Anarawad married to Cadwallader's daughter and killed in single combat with his father-in-law. [1037] Owain was incensed and sent his son Hywel to attack Cadwaladr's castle of Aberystwyth, but Cadwaladr escaped to Ireland. He subsequently fought both for and against Owain and spent 5 years in exile in Cheshire with his 2nd wife's family, being supported by Henry II with "honourable maintenance" see [50], [595] Eventually reconciled with Owen and even buried in a double tomb with him at Bangor Cathedral. Sometimes confused as an ancestor of the Blayneys [326], although his brother Owain Gwynedd was.

[304]. This convenient ?myth was used to support QEI's possession of North America.

Meredydd later became a monk and d.1244 at the Abbey of Strata Florida [833] He donated the land and materials for the Cistercian nunnery near Llanllugan sometime before 1188 [145] [597] Interestingly this nunnery was on the confluence of the River Rhiw, the site of the corn mill left by Thomas Blayney of Gregynog in his will to his son Morris indicating that this landhoplding was inherited by the Blayneys through Dyddgu, consistentent with her being the "heir of Meredith" [145]. Kevin McKenzie [145] further points out that many have incorrectly assumed that Meredith was the father, not brother of Dyddgu who married Meilir Gryg [40] [728] [707] 11 Dyddgu [a.k.a Jane] ferch Rotpert ab Owain [39] ("co-heir of Meredith" [39] [337] her brother and/or "sole heire of the Lord of Cedewain" [Blaines Descents [241]], suggesting she became the heir after Meredith took up the cloth) Brother of Meredith [842a], a.k.a. Jane ferch Robert Heraldic heiress of King/Prince Owain GWYNNED [see heraldry in the Gregynog Blayney Room and below] LODGE [707] has Dyddgu as daughter and heir of "Robert ap-Owen Gwyn ap Griffyth ap-Conan", consistent with her being the granddaughter of Owain Gwynedd Fawr Prince of Gwynedd, King of Wales 1137-1163 (then Prince of Wales until his death in 1169 as a concession to King Henry II of England).

The white Eryri
of Snowdon

Owain Gwynedd: Vert, three
eagles dispalyed in fesse Or

The white Eryri (eagle) on the green of Snowdon remains to this day a symbol of freedom to the Cymru. The "Blayney Room" Eagles have the more natural look of the Eryri than the modern styilized eagles on the Coat of Arms of Owain, but both, according to Kevin McKenzie "clearly represent the famous future-telling golden eagles of green Snowdonia as referred to by King Owain Gwynedd's c12th contemporary Geraldus Cambrensis". [145]. Kevin [145] describes the greenness "due to the high mountains breaking up the clouds" and refers me to Google images of Snowdonia to support this. Clearly kevin hasn't see proper mountains and real green as we have in New Zealand, but then neither had Owain Gwynedd!

Other genealogists & historians give her as the daughter of Robert ap Llowarch (Lord of Kedewen) or of Robert ap Dafydd ap Gwenwynwyn [496], [presumably meaning Prince Gwenwynwyn ap Owain (b~1151 r.1195 d.1216), the last great ruler of Southern Powys. however I can find no record of Gwenwynwyn having a son David, but I note that this pedigree actually belongs to Dyddu's daughter-in-law Alswn!]
The overwealming evidence now supports the Blayney claim for descent from Owain Gwynedd through Dyddgu [=Jane] being the daughter of Robert (Rotpert) ab Owain Gwynedd and that his illegitimacy was irrelevant because Owain acknowledged all his children as heirs.
+ Meilir "Gryg" ap Gruffudd, ancestor of the Blayneys. m~1197 10 Idwal ab Owain Gwynedd +(e)Nesta. Ledgend has the prolific Owain having a child with the beautiful Princess of Deheubarth (dau of Rhys ap Tewdwr) who had children also to: -Henry I (King of England), who "seduced her" while she was a hostage (for her father), Henry then "gave her" to -Gerald FitzWalter de Windsor who married her ~1100
"In Christmas 1108 Owain ap Cadwgan of Cardigan came to visit Gerald and Nesta. He so lusted after her that he, that night, attacked the castle and carried her off and had his way with her. This upset Henry I so much that the incident started a war." [600]
-Hait, Sheriff of Pembroke (?after Owain tired of her) -Stephen de Ceredigion (had the last dance)
