Mr.Cooper, I noticed your inquiry on this site last eveing. Maybe I can be of some help. William Sommerville died about 1874 in Grenada County,MS. His estate was probated in Winona, Montgomery Co.,MS. Mary Ann, his daughter, and her husband W.J.Trantham were living in Starrville, Smith County Texas at this time. Hope this will be of some help to you. My interest in this is that my GGGmother was Nancy Jane Sommerville born 1801 in Ireland and married to Robert Dobbins.I believe that she may have been William's sister. If I can help you in any other way please contact me. My e-mail address is firstname.lastname@example.orgGood luck in your hunting.
