You folks are industrious!
My cousin in Seattle does the family tree thing, but I've never really been interested. My paternal grandmother told my dad once we were related to King David. I have no idea how she figured it out.
Unfortunately, I'm a strong believer in the idea that DNA testing which can be accessed by "Agencies" whether legally or otherwise are much like having to carry ID cards.
No, I saw what happened to my family in Europe in the '30s. I'll keep away.
Young enough to remember doing it;
Old enough to wish I could do it again.
