Tami...My step-father was Henry Draper SIPPLE.I inherited a lot of information in the form of family history charts. My records match your information.William had a brother Boaz and sisters Leady, Elizabeth and Ruth.William, d. 17 Jun 1784, Kent, DE.William m. Catherine who d. 29 Nov 1764.William's father was also William SIPPLE of Kent DE...d. 26 Jan 1771, wife unknown.His parents were John SIPPLE, 1682-1752 and Susanna SIMMONS d. aft. 1729. John's parents were Garrett SIPPLE, 1653-1723 and Mary CALVERT, 1656-1698. My records indicate that Leady married BOOTH, but I can't tie him back to Waitman SIPPLE .If you can do that I would appreciate the information.
