The Votadini exodus to Wales

[Robert Vermaat]

The info or hint comes from the Truman manuscript in the Iolo collection. I know how you feel about the good old faker, but the Truman ms and the Saints ms do not seem to be in his hand.

hock: Hmmmmmmmm. Welll... I would put any money on that. Daughters, too, are most of the time 'invented' to claim supposed connections to otherwise unconnected families (plus their heritage).
Of course, that does not mean that such persons never existed, but see the Pillar of Elise(g) where an otherwise unattested daughter of Magnus Maximus crops up, to be married to Vortigern. Now IF that would have been a 9th-c. forgery, the forger took pains to use a very Roman name for the girl.
