Nathan, Have you had any success on proving that Jacob Yotsler's wife was Mary ENGLEMAN? Have you found their marriage date/place yet? Jacob Yotsler is my brick wall. My earliest "document" is his name appearing on a tax list (owning no land) in Hardin Co., KY. I do not know when he arrived in KY nor where he came from.
I don't know if his wife Mary was the mother of Susanna or not. I suspect Mary was the wife of Jacob's younger children born in 1790s, but perhaps not of Susanna since she was much older than they were. -- Helen Graves
