John Coats, Jr. was b. 10 Mar 1771 in Stonington, CT, son of John Coats, Sr. and Elizabeth (Stewart) Coats (I believe Eliz. was also a des. of John Alden). He mar. 1st Rebecca Brown, dau of Nehemia Brown and Rebecca (Lewis) Brown. They had children: Harris, b. 19 April 1795, mar Sally Stanton on 24 Jan 1815, d. 26 Dec 1875 in Pharsalia. (2) Betsey b. 1797, mar David Weaver; (3) Maria, b 1799, mar David Fargo. John and Rebecca moved to Pharsalia, Chenango Co., NY in 1799. They were given a lot, #36, a little west of the Center Church on which to build a cabin. There, they had another child, Edward, born 1803. He mar. Sally Stiles.
Rebecca died 31 March 1807, age 31 years. After a few months, John went back to Stonington, CT and mar. Lucy Peabody. She was the dau of Thomas Peabody and Ruth (Babcock) Peabody. The book, "History of Stonington" shows this marriage but in checking the Babcock family, the age give for Ruth Babcock does not make possible her being the mother of Lucy. Nevertheless, there may be an extra generation omitted from the history. John and Lucy returned to Pharsalia, NY. They lived together more than 50 years when she died 3 April 1857 at age 78 (?).
After they returned to Pharsalia, they had seven children: Almira; Alfred; Ezra; Charles Henry; William; Thomas; John. Although it is believed that John and Lucy lived the remainder of their lives in Pharsalia, it is believed that at least Ezra was born in Stonington, CT. He gives that p.o.b. on census forms.
My research follows the family of Ezra Peabody Coats to Byron, Kent Co., MI and doesn't follow Alfred and his family. Craig Coates would have that information and a great deal more.
The descent of John Coats, Jr. & Sr. is listed in a book, "The Genealogy of Robert Coates of Lynn, MA and Some of His Descendants" by Evelyn Aherin. This book takes John's ancestry back to the 17th century.
