Bartrum does not list who was the mother for Cadwgan's children, although he does list Cadwgan's wives (discount Angharad ferch Llawr, as she married Cadwgan ap Elystan of Powys) : https://cadair.aber.ac.uk/dspace/bitstream/handle/2160/5047/elystan....
Darrell Wolcott says that he has no strong opinion on the matter at this time. So:
Dwnn i, 271 shows Hoedliw to be the son of Efa ferch Gwrgan. Dwnn i, 313 shows all of Cadwgan's children (12 sons, 4 daughters) to be the children of Efa ferch Gwrgan, including Llewelyn ap Cadwgan. Dwnn i, 332 says Idnerth is the son of Efa ferch Gwrgan, as does Dwnn ii, 152.
Dwnn i, 313 assigns no children to Jane ferch Brochwel, nor does Dwnn ii, 152. Only Dwnn i, 139 assigns one child, Llewelyn ap Cadwgan (see above paragraph for same ) and misnames her as Elen.
Here in Geni we have assigned no children to Efa ferch Gwrgan. It looks like all children have been assigned to Jane, except Constance Wen, who married Efa's half brother, Iestyn ap Gwrgan ( so highly doubtful that Efa was the mother of Constance Wen.)
So I'm throwing this out there to see if anyone else has any source material to shed further light on this.
Hi, Steven Mitchell Ferry! Sorry it took me a while to get back into the Welsh lines.
Looks to me like we need to go with Dwnn in this case -- one of the advantages to Dwnn (can't believe I'm saying this) is that, though he does not reconcile the manuscripts, he at least says what they are. Yay.
On the other hand, he doesn't reconcile.
You asked for source material -- the manuscripts ARE the sources, and as you know, they don't agree all the time.
Am I reading this right, above, that basically Dwnn, in his transcriptions of the manuscripts, assigns all the children to Efa? does this include Constance?
I know I can go look up Dwnn myself -- but that will take a while, so I'm hoping to not have to. lol.
@Anne Brannen In one chart he assigns Llewelyn to Jane, and that is the only child attributed to her. There are multiple Constances all attributed to Efa, but none listed as Constance Wen. But that Constance married Iestyn, Efa's younger half brother, so doubtful that Efa was the mother of Constance Wen, and doubtful that Efa was the mother of ALL those other children. In my private chart I have Efa as the mother of Idnerth, Annes, and Iorwerth, but again, it is only a guess. I think I'm on solid ground with Idnerth, as one of the Dwnn charts deals specifically with his line.
