Hi Doris, I have a George Washington Duren born 1794 who Married a Sarah born 1813. Tennessee 1860 List their children as Margret, unknown 1841, Calvin 1843, Elisabeth 1846, Elisabeth 1846, Jonathan 1850, Thomas 1852, James 1854. This marriage to Sarah could be a second or third marriage. Because of the date of Calvin's birth George would have been 49 years old. I am trying to link this line to my tree Jonathan and Emily J. Duren and Their youngest son Thomas Jefferson Duren born in Mo. 1873.
