Well, looks like we're cousins!
My line is Christopher/John/Jacob/Joseph/Joseph
Smith (known just as
Smith)/George/Robert/Willard/Jane (my mom).
I still live in
Ulster County and have been to the old Manceville cemetery, or at least what was left of it in the early 1990's. Mostly hand carved slate stones. Christoffel had a wooden cross which I think has since disappeared.
