I am looking for my great-grandparents - Gustave Thalheim and Emma (?). He migrated from Wisconsin with his wife Emma and three young sons in abt 1915. He and Emma (last name unk) apparently divorced prior to 1917 and placed all three boys in an orphanage in Pocatello where they were adopted to the same family in 1917. At or about that time, Emma became pregnant and remarried (unsure which came first). Gustave registered for the draft in Pocatello, Bannock, Idaho in Sept 1918 and lists his next of kin as Mrs. Kathrine Thalheim in Plymouth, Sheboygan, Wisconsin. I do not know if she is his mother, sister-in-law, or second wife. Does this sound familiar to anyone in Idaho? His registration card lists his occupation as trucking and his employer as ODL Ry Co. Any guidance appreciated.
