The Vita secunda S. Winnoci (c. 1064), which gives the pedigree of the kings of Domnonia, and is composed of two segments a and b, states:
“Riwalus Britanniae dux filius fuit Derochi filii Guitoli filii Urbieni filii Catoui filii Gerentonis. Hic Riwallus, ad transmarinis veniens Britannicis cum multitudine nauium, possedit totam minorem Britanniam tempore Clotarii regis, qui Clodovei filius existitit.”
This suggests Riwal, who appears in segment b, belonged to gen. 0. I believe he was the father of Tristan.That Riwal was of gen. 0 is confirmed by Cartulaire de Landévennec, Cartulaire de Quimper and Cartulaire de Quimperlé. Those documents mention various dukes of Brittany. Conanus Sunnoc was Conan III. Alanus Hir Anger was Alan Fergant, i.e. Alan IV. Houel Huuel was Hoel II. Alain Canhiart died 1058.
Riwal’s sister, Pompaea who was the mother of Tudwal, is likely to be Alma Pompa, the mother of Leonorius. The former son was was a contemporary of Deroch II and the latter of Childebert. Breton tradtion states that Pompaea was married to Hoel Meur. This is chronologically possible according to Chronicon Briocense.
Now turning to segment a of the V. Winocci, the Chronicle of Fredegar indicates Judicahel was a contemporary of Dagobert, and so belonged to gen. 3. That Judicahel was of gen. 3 is confirmed by Cartulaire de Redon as his descendant, Roiantdreh, took prince Salomon, who was duke of Brittany from 857 to 874, as her adopted son when her son died in 861.
Jonas, who is listed in segment a, appears in Culhwch ac Olwen as Iona, king of France, a companion of Arthur. His father, Riatham, is Riothamus who Jordanes called the king of the Britains and who was militarily active around 470.
Aurilla, who appears in the V. Melori Martyris, is said to have been the daughter of Iudoc who belonged to gen. 3. This would suggest Melor was of gen. 5. However, it is more likely that Aurilla was the daughter of Rydoch ap Brychan as indicated by JC 2 11. DSB 11 11 adds the comment “in Francia” and a gloss refers to him as Iudoc. Brychan is of gen. -3 since his daughter, Meleri, was married to Ceredig ap Cunedda Wledig.
