I don't have a great facility with these genealogical charts, but it looks to me as if I am also descended from Peter Elzey (d. 1716, Somerset Co., MD). Our most recent common ancestor was William Elzey (1761-1830). You're descended from his son Arnold (1796-1873) and I from his son Charles (1795-1881). I have visited Charles' grave in Sharptown, MD. From there, my descent comes down through Robert Martin Luther Elzey, Ara Elzey Caulk, Sadye Caulk Nuttall, and Charles Edwin Nuttall, Sr.
