Wow, you found a lot of interesting stuff. Your experience with loyalist materials may really pay off for us both.However, lets start with the material about the Harrison family after which the town of Harrison in Westchester County was named.It never occoured to me to look into this (Harrison being a common name) but it turns out this family is heavily interconnected with the Sands family. You mentioned that Joshua Cornell married Hannah Harrison, the daughter of Samuel Harrison (who, also resided in Harrison's Purchase), the brother of the John Harrison after whom Harrison is named.Again, I had to trace out the connections. The Joshua Cornell who married Hannah Harrison was the son of Joshua Cornell and Charity Haight (you mentioned the Haight family as one of the other origninal owners of Harrison's Purchase).The Joshua who was married to Charity was the son of Joshua Cornell of LI who was married to Sarah Thorne. One of their grandchildren was Martha Cornell, who married Henry Sands(#50 in Wilson). This Joshua Cornell of LI was the brother of Richard Cornell, whose daughter, Mary, married Edward Sands (#11).He was, also, the brother of Caleb Cornell, whose daughter, Elizabeth, married John Sands III (#35). He was, also, the brother of Mary Cornell, who married James Sands (#6). James Sands and Mary Cornell were the parents of Othniel Sands (#23) of North Castle and Mary Sands (#24), who married Joseph Sutton of the North Castle Suttons.
If I recall correctly, many of the Westchester Cornells were Quakers, as were many of the Westchester Underhills.
In the course of tracing this out, I, also, tapped into the Dodge family material.Jeremiah Dodge who married Elizabeth Sutton appears to be of the Dodge family of Cow's Neck (Sands' Point). The exact relationship is not known but there are loads of Jeremiahs in that family (see "Willis-Baker 25 Sept 2002" tree on Ancestry/rootsweb). The patriarch is William Dodge who, apparently, resided on and was married on Block Island. One son, Wilkie, married Mary Hunt and their daughter Sarah, married Comfort Sands (#102). Another son of William, Jeremiah Dodge of Cow's Neck, had a son Tristram, whose son, Stephen, lived in Westchester and became a loyalist (swithched sides) who died in Wilmot, Nova Scotia in 1808.
I think there are just too many connections here to be coincidental.
Turning to your loyalist research, it appears that Clark was unable to identify where William Harrison was from, since he lists only the town in New Brunswick.When I had heavy subrsciptions to Ancestry, I believe I saw references to William Harrison as serving in NJ loyalist regiments. Next time I go to NYGB&S I'll check (there is also a reference to him in the NYGB&S Record that I want to go back and re-read at Vol. 37 pages 13 and 110). I didn't save the research because, at the time, I didn't know that William H. Harrison's sister might have been born in Canada.Incidentally, New Brunswick is problematic for me as a residence for Sarah's parents. According to the Calender descendant, Sarah (Harrison) Callender's son's death certificate lists his mother's birthplace as Nova Scotia. The family bible so indicates as well.
She was born on Sept. 15, 1780.Do you know if there are Nova Scotia birth records I could check from this period? It is possible that William H. Harrison did not go with his father to Canada, as he was born in April 1768. I do not have a birth date for the other sister, Mary.All three were married in NY. William H. was married in Jan. 1800. I do not know the precise dates for the other two but Mary's oldest child was born in 1804 and Sarah's oldest child was born in January 1799.
That's all for now. Thanks for your help and I will continue to work on both our issues. It seems more and more likely that they are related.
