Hi. I'm not related to this family.I'm sorry I did not find an obit for Theda, but I did find her marriage:
Date: 1944-04-09; Paper: Oregonian
Vancouver Marriage Licenses:
STOKES-DESCHNER - Claude L. Stokes, 45, 5514 N. Missouri, and Theda N. Deschner, 41, 1634 S.E. Hawthorne, both of Portland.
So, this is probably Theda in 1930:
1930 United States Federal Census about Theda N Deschner Name: Theda N Deschner [Theda N Silvey] Gender: Female Birth Year: abt 1903 Birthplace: Oregon Race: White Home in 1930: Portland, Multnomah, Oregon View Map Marital Status: Divorced Relation to Head of House: Daughter Father's Name: Perry L Silvey Father's Birthplace: Missouri Mother's name: May C Silvey Mother's Birthplace: Texas Household Members: Name Age Perry L Silvey 56b. 1874 Missouri, par b.

Here is an obit for Theda's mother:

SILVEY - Jan. 16, May C. Silvey of 4848 NE 11th; beloved mother of Theda N. Stokes, Ruby Mae Spencer; grandmother of Eldon Spencer... Interment, Rose City cemetery, EA 4111.
Deschner was NOT Theda's married name.Here she is in 1920:
