According to my father's sister, they had the direct decendant from Scotland's info somewhere, but no one would ever send us the info and I have not been able to find it myself. My father was the youngest of 10 children and he's 84, and only has his sister left who is not in good health, her mind started slipping long ago, so unless I can find the parentage of my great great grandfather I'm screwed. I have seen William Campbell Smith come up many times in my research though. (I've spent hours pouring over ancestry.com and google searches.) I do want to, before my father passes pay for the paternal DNA testing to see what that reveals. I think it would be interesting.
Yup, that's my side, lol... I may still have some things I can look through, might find something, ya never know... used to have tons of geneology on our family, my grandma spent most her life on it... lost most of it after she passed and he remarried so new wife inherited...
