In the 1850 census of Wilson Co.,There is a listing of Sarah and her six childrn. Your Nancy was 15. It lists a John W.F. age 2. He is actually John Thomas who is my great Grand Father. Sarah and her brood came to Texas with the elder Edward in early 1850's. They settled around Waxahachie. If you look under Ellis Co. cemeteries you will find a Sweatt cemetery listed. There should be a link to pictures. Sarah and family left there and moved to Parker county outside of Weatherford. She is buried along with two of her children and John T.'s 8 year daughter in the Ballew Springs cemetery. I found their graves several years ago and have been taken care of them since. I live in Arlington and am close to both. Are you in Texas?
