I have never taken as "certain" anything anyone else says about this stuff. Not long ago I was given some "good, sourced" information about a line I've been working on, that I, in good faith, added to the profile. On later reading and comparing I think the cousin was wrong, because of what the census actually says. (Jumbled statement, I know.)
Point I'm trying to make is .. while I accepted the information and added it, I have since edited in my doubts that it refers to the person of the profile.
It IS possible that the information you're accessing is incorrect, so don't stop trying to find everything else you can that will lead to the facts. :)
