I'm researching a John Milton Mahaffy (or Mahaffey - not sure of the correct spelling). He was born abt. 1880 in New York (according to the 1910 US Federal Census). Places of residence include, besides New York, Marengo, Iowa Co., Iowa; Marion, Linn Co., Iowa (where he was an assistant principal at the high school in Marion), Decorah, Iowa, and Manteno, Kankakee Co., Illinois where he was a pastor. He married Elizabeth "Bessie" Roberts (1885, Iowa - 1912, Iowa) in 1904 at Marengo, Iowa Co., Iowa. They had three girls: Elsie (b. 1905, m. [--?--] Wilson), Ruth Eileen (b. 1907-1910) and Martha Josephine (b. 1910). Any info appreciated.
