I am looking for a Wm J Keenan (or Kenon, Reenan) who came from Ireland, probably died between 1880 and 1910. He married Martha Polly Ann Justis on May 4, 1882 in Springfield, Greene Co., MO. They had children: Ida, Alice, James. It is believed that both parents died before 1890 leaving the children to be raised by their maternal grandmother. I can't find them on any census or any death or burial records. If anyone can lend a hand it would be much appreciated. Thanks.
