Mareen Duvall "The Younger" bornabout 1680 was married to Elizabeth Jacob in 1701. Of the seven children, there was Jacob Duvall born 1715. He was married to Mary _______about 1749 in MD. Could she have been Mary Miles? I have come to the same conclusionon the ancestry of Mareen Duvall However I do conceed that it has not been proven. How did you find that Adelina de Beaumont was the wife of Sir High Duvall?
