Well, I haven't given up completely yet - but nearly ready to. I've added most of his primary tree (parents, grandparents, brothers, sisters, etc.) where there were gaps, and as much of his extended family as I could (total of 59 profiles as of now) and unfortunately, no connections. I did find a couple of modern ancestral connections, but no links.I'll probably add a few more to see if something shakes loose, but at this point, I'm coming up empty as far as connections go.
