John had three children by his first wife (unknown): Lydia Ann, born 10 Oct 1839 and Mary J born 1843. John married Emily Weld Durgin in Sanbornton in 1844. No parents were recorded. John and Emily were recorded in Pittsfield in 1850. I am seeking the name of John's first wife and place of marriage and birth of children. John and family were found in 1860 in Liberty Township, Iowa
