Cheryl, Where in Iowa are you searching? Are you looking for descendants of Joseph b. 1748, MD. There are two branches of these Downings living in Guthrie Co., Iowa that claim to be distant cousins to each other. I have traced both back, one to Joseph and the other to Mary that had a twin sister Elizabeth that married James McClelland. I will be glad to share what I have. Guthrie is the same Co. that my Williams two daugters came with the Miller family in mid 1800's. My Grand-father came to Guthrie Co., Ia. and lived with his aunts. The families I mentioned descended from Joseph 1748 and my Grand-father knew each other but didn't know if they connected. So far I have not proven that they connect. Ruby Waugh, Iowa
