Seeking help with William L. Gearhart born in Pennsylvania in November 1894 to George Gearhart and Ann Lindsay. Later the family moved to Detroit where William registered for the draft in 1917 and then married Anna Siemowski on 30 August 1919. William and Anna appeared in the 1920 U.S. census in Detroit. On the 1930 U.S. census Anna appeared as a widow living with her birth family. She was still a widow on the 1940 U.S. census. Cannot locate any death record for William, and Anna drops out of sight. Any suggestions?
