According to the April 1971 NEGHR article "Richard, William, and Hugh, Sons of John Briggs of Taunton, MA" (by Edna Anne Hannibal and Claude W. Barlow, Ph.D, F.A.S.G), pg 87: William BRIGGS (William2, John1) born in Taunton 25 Jan 1667/68, & died there 20 Feb 1731, aged 63 years (g.s. Oakland Cemetery reads "in 64th year"). He married first, in Taunton, 13 [or 17?] Oct 1693, Elizabeth LINCOLN, daughter of Samuel Lincoln, who was born in Taunton, 24 April 1669, & died there about 1695. He married secondly, in Milton, Mass. 16 Jun 1696, Mehitable BLAKE, daughter of William2 (William1) and Anne BLAKE, who was born in Milton, 2 Apr 1673, & died in Taunton 7 Oct 1732, in her 62nd year (g.s. Oakland Cemetery.) I show Mehitable as the eleventh and youngest child of William and Anne [or Anna LYON] BLAKE. William BLAKE was born 6 Sep 1620, in Pitminster, Somersetshire, England, (a son of William BLAKE and Agnes THORNE) and died 3 Sep 1703, in Milton, MA.
I am very interested in comparing the marriage and death information for Seth's children. Would you post what you have?
