It'll take me a while to copy over the documentation but here's the basics. William Amazeen married (Newcastle VRs) first Jane Jones Amazeen daughter of his cousin, Nathaniel Amazeen, and Sarah Jones. I'd bet that they were that young as we too show them filing intentions in NewCastle NH 29 April 1804 and theirfirst child being born 5-6 months later. Their 16th child was born 3 Feb 1832 and if she was bearing children for 28 yearsshe probably started fairly young.She was either 61 or 62 when she died depending on the sourse. William married second (DE, 1March1853; RM, 2March1853;DG 5March1853; PJ, 5March1853), Frances (Trefethen) Sterling, the daughter of another cousin Dorothy Amazeen and Daniel Trefethen.
