I don't have any connection between the two. I have several McClellans in my family tree. Amongst those are two Abrahams. Abraham M. McClellan and his grandson Abraham, son of Wilson McClellan. I also have one Brodie in my family tree. That would be my great aunt Esther Vernice Brodie. She was marries to James Russell Exline. I have nothing on her ancestry. I also have one Graham. I have a Mary Graham married to Nelson Jolly back in the mid-1700's. Does any of this help?
