Hi...I was wondering if by chance your Sthal is the same as my husband's maternal great-grandmother Mary Sthal. They lived in Nebraska and she married Charles Olsen. They had 7 children, I know the names of some: Minnie (my husband's grandma), her sister, I think a twin, Ingrie, Alvin and Paul Olsen.
Will look forward to hearing from you.
