Patrick's parents were Zachariah Cassady and Mary Idly (according to Patrick's family bible). But I'm sure they were not married in Ireland. Zachariah fought in the Rev. War and is listed as from S. Carolina. In the 1790 census, Zachariah was married, but had no children. I have no information on Mary Idly, other than what is listed in Patrick's bible.I've been to Ireland, talked with genealogist there, and can not find the connection to the S. Carolina Cassadys.
