Hi Jody, Thanks for your input. I believe that there were 2 John Sawtells in Groton, MA during this time. The first one, the last child of Ephraim and Abigail was b. 18 Apr 1729 ( as you pointed out is found on p.432 of the History of Groton book) and the second one, the last child of David and Elizabeth was b. 17 Jul 1743.The second one is referred to as John Sawtell, Jr.I think that the Jr after his name is very important. (This means that he was the younger of the two, not that he had a father by the name of John as we would use it today.)John Jr used this signature even when he bought land in New Ipswich, NH in 1771. The first one stayed in Groton and died there in 1790.The tombstone in Groton states: "Captain John Sawtell, d. 23 Dec 1790 at age of 61"!So my math says that he was b. in 1729.Definitely not the same person who was b. in 1743 and died in NY. I can't find a marriage for John (Sr) in the Groton Book or in the NEHGS vitals records for Groton. I did find a two probate papers for a John Sawtell in the Middlesex Co Probate Index (NEHGS source).One for a guardian for a John H Sawtell, 1788 (#19,915) and another for administration for a John Sawtell, 1791 (#19,961).The actual papers are found in the FHL microfilm # 421,513 for the Middlesex probate papers of #19,867-#19,961.I suppose that I could order this film and look at both of these papers.Or maybe two of us should do it to check our information. Let me know.
Anyway, my evidence suggests two John Sawtells of Groton from different families, different birth and death dates, and different migration patterns.
