In your post you mentioned the daughter of Judson & Leota WILLHELM as Erma Kate WILLHELM born 1919 and died August 30, 1992. May I ask your source for that info? Are you certain that Erma Kate is their daughter? Perhaps you got that data from a family Bible or personal records? Or did you know her maybe? Did you get your info from the Social Security Death Index online?

The reason I ask is, I found an Erma Kate WILLHELM in the Ohio Death records but it indicates her father's last name as something other than WILLHELM. I've copied the record below from the website. It appears this Erma Kate was a WILLHELM by marriage only:
