Arthur’s descent from Cunedda

Gwen, the supposed mother of Eigr, is said to have been the daughter of Cunedda Wledig, see Amlawdd and Gwen. Arthur is identified with Paternus on the Tintagel slate. The V. Paterni tells us that Paternus’s mother was a lady named Gwen (Guean) but does not give her ancestry. This is provided by a late addition to the ByS in the manuscript Pen. 128:

Gwenn v’ch Karedic ap Kvnedda wledic

The respective pedigrees are shown below:

Gen. JC 7, ByA 29(13, 14) ByS Pen. 128 Reconciled
0 Arthur Paternus Arthur/Paternus
-1 Eigr Gwen Eigr Gwendragon
-2 Gwen Ceredig Ceredig
-3 Cunedda Cunedda Cunedda

Arthur’s pedigree may be reconciled with that of Paternus as follows. Gwen was not the mother of Eigr and that name was part of her cognomen as shown in column entitled ‘Reconciled’ in the table above. The evidence for this assertion is provided by two Irish Arthurian Romances. In the RIA.23D 22 version of the Romance Eachtra an Mhadra Mhaoil (The Story of the Crop-Eared Dog)[1] we have:

Artur mhic Iobhair mhic Ambros mhic Constaintin

whereas in the RIA.23M 26 version it is:

Arthur mhac Ambróis mic ConstantÍn mic Uighir Finndrea guin

In the Romance Eachtra Mhacaoimh an Iolair (The Story of Eagle-boy)[2] the last name in the above pedigree takes the form Ughdaire Finndreagain. These pedigrees are consistent but need to be interpreted thus:

Gen. EaMM RIA.23D 22 EaMM RIA.23M 26 EMaI
0 Artur Arthur Artur
-1 Iobhair [Iobhair] Uighir Finndreaguin Iubhair Ughdaire Finndreagain
-2 Ambros Ambróis Ambrois
-3 Constaintin ConstantÍn Constaintin

So, Arthur’s father, Iobhair, was the son of Ambrois (Ambrosius) who in turn was the son of Constantin (Custennin Gorneu). Moreover, Arthur’s mother was Uighir Finndreaguin (Eigr Gwendragon), where Irish Finn and Welsh Gwen have the meaning white or fair or blessed. Finndreaguin was erroneoulsy taken to be Cinndreaguin, resulting in the matronymic Arthur m. Uighir Finndreaguin becoming the false patronymic Arthur m. Uther Pendragon. Another inaccuracy is the assertion that Eigr’s father was Amlawdd Wledig. As noted by Brynley F. Roberts[3] he is a fictitious character whose only role is that his daughters are the mothers of heroic figures.

Amlawdd and Gwen

JC 7 states that Cunedda Wledig had two daughters, Tegid and Gwen, the latter being the wife of Amlawdd Wledig:

D6y verchet Cuneda Tecgygyl A Gwen g6reic Anla6d wledic.

ByA 29(13, 14) agrees with the above, adding that Gwen was the mother of Cynwal Garnhwch:

Dwy ferchet Kunedda: Tegit, Gwenn ferch Kunedda gwreig Amlwyd wledig, mam Kynwal garnhwch.

Amlawdd and Gwen’s son Cynwal Garnwch appears in CO as Kynwal Canhwch, the father of Gwen Alarch whose name means White Swan. Bartrum in WCD says Kynwal’s name appears to be the Welsh equivalent of the Ulster hero Conall Cernach. Cynwal may have been given this name as it was also that of Amlawdd’s own father.
