This is apparently an established royal line outlined in Gary Boyd Roberts' "Royal Descents of 600 Immigrants" but I'm attempting to verify it with contemporary primary sources which in my first blush I haven't been able to do. His sources appear to be secondary? I'm not saying the proof's not out there at all, but just thought I'd post here to see if anyone's already traveled this road and verified independently.
In near-contemporary bios of Gov. Patrick Henry there's mention that his grandmother was "the sister of Rev. William Robertson" which many have taken to mean the son of William Robertson of Gladney and father of William Robertson the historian.
I've found a letter from Margaret Donald to Gov. Patrick Henry, written in 1790, and she tells him his ancestry at the insistence of their cousin David Henry (presumably the one who went to London and worked with Edward Cave on the Gentleman's Magazine) and she only lays out from his grandparents and down and makes no mention that his grandmother is related to such a prominent historian as William Robertson.
I see that there are "papers related to family history" in the William Robertson papers at the National Library of Scotland, but whether these are related to his own family, or families he researched for his publications, I don't know. I'm considering hiring a local genealogist there to take a peek for me, but before I went to that expense I wanted to float this family here on this board to see if anyone had any insight.
