Hello Marian, I found what happened to Cleopatra (STUART) LAYMANN SHEPARD, daughter of William and Nancy STUART.
The marriage I found for you earlier, between Cleopatra LAYMANN and Alvin Gates SHEPARD, is your cleo.
Cleo's 2nd husband, Alvin Gates SHEPARD, died 11 December 1939, in Salem, Marion County, Oregon. His occupation was listed as Service Station operator. His death certificate says he died in Salem, "State Cap. Bldg." His residence is listed as Dayton, Oregon, which is in Yamhill County. Alvin is buried with in the same cemetery, and plot as his first wife, Belle. It is the I.O.O.F. Cemetery in Dayton, Oregon.
The residence listed on Cleo's death certificate says 7657 S. E. Hawthorne Ave., Portland, Multnomah County, Oregon, so she must have moved back to live with her sister after Alvin died in 1939. The name on the death certificate was Cleo SHEPARD and said she was a widow. Cleo died 6 February 1947, in Portland. The informant was C. H. AGER, husband of Oma M. (STUART) AGER.
