I am looking for Oscar Hiatt after 1943. He was last noted signing a land document in Kingfisher County, Oklahoma in 1943. In the 1940 US Census he is living with his widowed Half-sister, Emma (Hiatt) Umberger in Lacey Township, Kingfisher County, Oklahoma. Emma died in 1950.
Background on Oscar Hiatt:
Born in Indiana in 1868 (Father was John Hiatt)
First wife was Ola Knox and they had 3 sons (Glenn, Clyde, and Frank - note Frank was put up for adoption and adopted by Plants in Ohio. Ola died in mental hospital in 1911 and Oscar then married Emma Oliver in 1912. They moved to Washington County, Arkansas (1930 US Census). Oscar lived there until at least 1937 when Emma died.
Oscar then is seen living with his Half-sister, Emma (Hiatt) Umberger (1940 US Census lists them both with last name of Umbarger).
