Rosalie Noland Ball, a Powell descendant, published a genealogy of the Powell family in 1938. My great-grandmother purchased a copy which I now have. For some excerpts from this book, go to my website at http://freepages.genealogy.rootsweb.com/~susanb/powell_family.htm and click on "Excerpts from Rosalie Noland Ball's book of Powell genealogy". Page 13 of this book can be viewed on my website (see URL above). This shows early generations of the Powell family. Walter Powell was transported to VA by Capt. Samuel Mathews (a Quaker) in 1643 and later relocated to Somerset County, MD. Walter Powell m. Margaret Berry 1666 they had 7 children, including William 1673-1715 William Powell married Elizabeth Lane Their son William Powell Jr. married Eleanor Peyton, and Col. Leven Powell (married Sarah Harrison) was one of their children. Another son of Wm and Eliz Lane was Levin Powell d. 1764. He had a son named Levin H. Powell who married Elizabeth Cohagan. Many duplicate names in this family, but it appears as if the Levin H. Powell who married Elizabeth Cohagan was a cousin of Col. Leven Powell of Middleburg. There's no indication in any of this material that Col. Leven Powell's first name was John. Hope this helps! Susan Buyer Potomac, MD
