"Elizabeth (Griswold), b. 20 May, 1682; m. 12 May, 1699, Michael Griswold; d,. 9 Sept. 1741."
This marriage occurred in 1692, not 1699 by which time the couple had three children, the eldest born 1693. Since she was married in 1692, she was quite obviously born somewhat earlier than 1682.
'Michael Griswold, son of Michael and Ann, was born 7 January 1667 and died 1744. He married 12 May 1692 Elizabeth Burnham who died 9 September 1741. Lived in Wethersfield, Conn.'
