I, too, am seeking the ancestry of Captain William KIDD. All I know is that he was born about 1645 in Greenock, Scotland. His father was John KIDD, a Presyterian minister. His mother's name is unknown. In 1691 Captain KIDD married Sarah BRADLEY COX OORT, a wealthy widow who had daughters by previous marriages. I do not know if he had children of his own. I have contacted the author of a book on Captain KIDD -- he knew nothing more than this.
