Hi - Just read your post. I have the "English & American Wentworth Genealogy" books and found John Wentworth's info.
"John (5) (715), son of Spencer (4) and Sarah (Stiles) Wentworth, born in Wakefield, N.H., April 1781; moved to Hiram, Me. He married, 28 September 1806, Esther Hall, of Standish, Me., born 1 March 1788. He died in Hiram, 16 Jun 1827; She died there 23 February 1865. They Had: Eight Children
Spencer(4) (262) (John's father), was the son of Ephraim(3) and Martha (Grant) Wentworth, born October 1739. He was in the Revolutionary army as early as 1775. He married, 1st, 14 December 1769, Sarah Stiles, of "Sligo," in Somersworth, N.H., and near South Berwick, Me., who died October 1809; 2d, widow Sarah (Welch) Bryant. He died in Wakefield, N.H., 20 June 1816. He had, all by his first wife: Eight Children including John(5).
Hope this helps some. Virginia Harris
