They might have been from York County, SC. My great-grandfather, Martin Rowan HULLENDER, b. 1845 York County, SC, married 1866, Lumpkin, GA, named a son Judson Clemonts (Clemons). I have wondered about this choice of a middle name. I do not know the maiden name of Martin Rowan's mother and continually search out all the given names of the family that might be surnames. Other possible surnames-for-given names in the HULLENDER family have been Thompson, Martin, Rowan, and, of course, Judson. Do you see a connection?
