Thomas Warren of Surry County Virginia was my eighth great grandfather. Elizabeth Spencer was his second wife, my eighth great grandmother having been Jane Allen. There is some information in the book Purse and Person, First Families of Virginia about Thomas and Elizabeth and their children. You might find what you are looking for there. I also have the Warren line going back as far as 90 AD. Thomas was descended from a line of Frankish Kings. Would be happy to share this information if you like. Also know quite interesting things about Thomas and Elizabeth and her father.
