James Nisbeck lived in Fonthill Gifford. He married Margret Snook on Jun 5, 1775 there. The family had 4 kids. (I'm probably missing a few, it's hard to find the spelling variations.) Martha b. 1772 baptized 1775, Morriah bap. 1777, Jacob bap. 1779, and Susannah bap. 1787.
I'm trying to find a burial date for him, as the surname Nisbeck isn't very common in the area.
