I popped over to the Archives today (also home of the Historical Society) and copied all the trees from the Sutton file.I am e-mailing them direct.The best tree for your purpose (undoubtedly the one cited by Mary Beth Wheeler) is on top and was done in 1988 by Dick Lander, North Castle Historian.Sands Sutton died young without significant property. I confirmed that there is no estate proceeding in the Archives. His father, Joseph Sands, married Deborah Haight. I assume this is the Quaker Haight family which was one of the original partners with John Harrison in Harrison's Purchase. One book I read about the region says that North Castle was settled by military men who were Episcopaleans and came over with the Duke of York.
Joseph had several children but no one seems to have a complete list. Lander mentions that the book, Westchester Patriarchs by Norman Davis, which you cited to me in your May 14 post to this Board, lists several but he feels that some are listed in error.
Lander only mentions one child of Sands Sutton,James. The 1790 census, cited by Lander, suggests that this may have been his only child. Although Mary was a very common name among the Suttons, none of the trees provide an answer as to the Mary Sutton who married Joseph Sands.
Turning to the Harrisons, the reference to William Harrison, Waggoner to His Majesty's Royal Artillery is in a wedding license issued by the Secretary of the Province of NY on April 20, 1780 for the Marriage of William Harrison and Sarah Bennet, NY Spinster. This is contained in O'Callaghan, E.B. "New York Marriages Previous to 1784" pages 534 and 548. The Family History Center web site indicates that the marriage ceremony was held at Trinity Church in Manhattan. A copy of those records is at the NYGBS Library so I will look there to see if it provides any further clues.
Any advise as to where to learn more about this Loyalist William Harrison would be appreciated.
