I thought he was geniuinely interested, although I got the impression it hadn't all sunk in. I don't think it would all sink in for me if all my research was presented to me and I hadn't seen it before. No matter who your ancestors are I reckon it would be a bit much to take in all at once. I mean what I know so far about mine I have uncovered gradually over 17 years and even then I have "oh wow really" moments.
Did I misread? did someone say he wasn't directly descended from Edward III? he was his 22nd grt grandfather, to me that is a direct ancestor. Indirect would be grt aunts and uncles etc.
I also think the number of 22grt grandparents we have will be complicated by the likelihood of cousins or second cousin marrying at some point over 22 generations making some grt grandparents related twice over, or more.
I am jealous though, would love to know who my 20xgrt grandparents were.
