Hi Rachel,
Thanks for having these profiles in WikiTree. It makes it easier to collaborate.
I've said recently, elsewhere on the forum, that it really helps to start documenting what you *think* you already know about existing family members.
I'm not seeing much in the way of sources for this person, his daughters, or their children. It just says "Ancestry.com" without a link. Something about Find A Grave, without a link. And a link to a personal family website that requires registration.
It makes it challenging to help you in your search, if you've already done research elsewhere, but we don't know anything about it, or can't get to it.
Have you looked into some of the free genealogical resources to find sources for these people?
