My line it through John Sumpter & Catherine Van Pelt, parents of Betty Sumpter.Betty married Richard Ramsey in 1781.
Your Cpt William Sumpter is brother to my John Sumpter.You will find your info on the first link I have listed below. I had posted these links on a previous message on the Sumpter website, but since then I have found one more site of interest so check out my #6 item below.
Here are some links where I have found more info on my Ramsey & Sumpter line.
Check out the links below to view this info:
1. http://genforum.genealogy.com/sumpter/messages/180.htmlhttp://genforum.genealogy.com/sumpter/messages/180.html This site show's Betty's Sumpter's parents as John Sumpter and Catherine Van Pelt. John Sumpter's parents are listed as William Thomas Sumpter & Elizabeth Iveson, both from England.
4. http://genforum.genealogy.com/sumpter/messages/31.htmlhttp://genforum.genealogy.com/sumpter/messages/31.html This one identifies the wife of William Sumpter as Elizabeth Iveson but it states that she was married once before, so it's questionable if Iveson is her married or maiden name. Also this one has info on William Sumpter's death record ***
