I am also from the Jacob O Siler b-1770 line, but from there we are from his son Adam's May 27, 1796 - October 23, 1881 line. I can take you from there to here if you'd like. Adam's wife's name is where my name comes from... Mary "Polly" Brock Siler
Let me know.I am very interested in all of it. I want to know the branches.
