Interesting. However, not to rain on your parade or anything, but it's been my experience that the books of Weiss and Roberts fail to provide sufficient documentation to be little other than yet more recitations of 'family lore' tales.
Even the signed report we presently have to the effect that Robert Abernathy (1632-1685) of VA was the son of George Abernethy de Barrie is all but worthless since the lady who left that document in the Library in Lincolnton, NC did not give sufficient information on her sources. She gave a conclusion (one much desired), but her signed statement was tantamount to me saying I searched the Library of Congress and I found [whatever claim you want]. Sorry, but even an amateur genealogist should do better than that.
If a researcher cannot follow along behind another researcher and access the same sources on which the first party based their conclusions, it's no better than giving a press conference to the world claiming you've discovered cold fusion. If nobody else can duplicate it, it's useless.
No documentation to support a claim equates to a verdict of 'not proven' and a worthless claim.
