My mother, Margaret Ann Cotnam was born to Hallah May Ball Cotnam and William Alfred Cotnam on September 25, 1910. Just found this: Ann Pamela Ball born March 13, 1866, Warren County, Iowa. I can't seem to put all this together?? I found this infor-mation on old scraps of paper my grandma left in books and letters. I do have a copy of Warren County,IA, history dated 1879. Can't find any Cotnams in it???
