The line of descent of the Venedotian kings is given in H3859 1. However, this list poses a problem in terms of chronology until it is treated as two fragments as shown in the first and third columns in the table below. The reason why I have inserted a second column in between will be explained.
|Gen.||H3859 1:1st seg.||H3859 1:2nd seg.||H3859 1: 3rd. seg.||ByA 28c||ChB|
|4||Cadwaladr F.||Alain II|
|1||Iago||Rhun H.||Perweur||Alain I|
|0||Beli||Maelgwn G.||Rhun R.||Hoel II|
|-1||Rhun||[Einion]||Cadwallon L.||Einion||Hoel I|
As can be seen in the first column, the list states that Rhun was the father of Beli. This is correct but that individual was not Rhun Hir, the son of Maelgwn Gwynedd, who appears in the 3rd column.
Rhun Hir married Perweur f. Rhun Ryfeddfawr whose name appears in ByA 28c and they both belonged to gen. 1 as shown in the above table. Triad 79 tells us she was one of the Three Lively Ladies of Britain. ByA 28c errs when it says Perweur was the “Mam Beli m Rhun …”. As can be seen from the first column Beli m. Rhun belonged to a generation one earlier than that of his supposed parents. ByB confirms that a Rhun was the father of Beli. It was this Rhun and not Rhun Hir who fled to Armorica. His daughter, Tymyr, married Hoel II who appears in ChB.
HRB wrongly asserts that an Einion was Beli’s father but I believe it contains a germ of truth in that he was his uncle. Both HRB and ByB assert that Einion was Rhun’s brother and this is depicted in column 2. However, although those documents claim they were the sons of Maelgwn, I suggest their father was Einion Yrth. This allows us to solve a 1500 year old murder mystery which is not a whodunit but a “who was it dun to”, as we know the identity of the murderer but it is unclear who the victim was. Gildas wrote of Maelgwn:
In the first years of thy youth, accompanied by soldiers of the bravest, whose countenance in battle appeared not very unlike that of young lions, didst thou not most bitterly crush thy uncle the king with sword, and spear, and fire?
In the Latin text the word for uncle is avunculus which strictly means mother’s brother. However, in this context I believe this can be linked to the fact given in JC20 23 that Einion was not only half-brother to Cadwallon Lawhir, Maelgwn’s father, through Einion Yrth but that their mothers were sisters, daughters of king Didlet.
Although HRB states Rhun escaped to Armorica after the death of Einion because he was driven out by the Saxons, it would seem that Maelgwn had a hand in it as well. After Maelgwn’s death his son successfully thwarted challenges to his kingship. However, it would seem that the rightful lineage to the throne was reestablished when Beli became king. As can be seen in the above table, Cadwallon is correct when he tells Salomon II in ByB that their two fathers were two second cousins.
