I am trying to find names of parents for both/either Theodore E. Rietesel (B.May 22, 1913 in Cook, Illinois) and Clare Louise Youngs (born 1927 in Illinois) Clare was the wife of Theodore. Theodore's father's name may have been spelled Rietzel. I know there was a change in spelling sometime around immigration, just not sure which generation.
These were my grandparents, and since I have no contact with my birth father, I'm having trouble finding more info.
Any help with these names is appreciated.
