I have a W.M. Robertson who was the son of Edward C. Robertson and Elizabeth Jane Ingram of Coffeyville Area. Edward was born in 1824/25 in W. Virginia & died 1899 in Montgomery Co. KS. Elizabeth was born in Nashville, TN 6 Sep 1827, daughter of Thomas Ingram (b. 10 Dec 1803 in Knox Co. TN). Elizabeth Ingram was married to Edward C. Robertson 28 Jan 1847 in Moniteau Co. MO and she died 20 Oct 1904. They had six other children, one of whom was Nancy Arlie Robertson (my great grandmother). There are several Ingram leads in the Knox County TN area in the 1800 time frame but I have no leads on Edward C. Robertson's ancestry.
