Sarah: Double checking on something. I show that Nicholas was the son of John Sebastian who married Anna Marie bowman.I show that John Sebastian and Anna Marie were married in 1766. I also show a Margaretha born in 1752 who married a Jacob Kisner who had a daughter named Catherine who married a Daniel Hill. If I am right, probably Margaret Seybert isn't a sister to Nicholas, son of John Sebastian, since he and Anna Marie weren't married until 1766. I don't know who Margaretha parents were, do you?
