My great grandmother was Agusta. She married Henry Strehlow in Kewaunee County Wisconsin.
They were German and Henry had married Emily first and they had 5 children. Emily died and because it was the custom Henry married Agusta as she was unmarried. They had 5 more children, my grandmother Elsie was the youngest of the 10. Amanda was the oldest of the 10.
I cannot find anything other than their marriage and death.
I am not prepared with info (and I have a lot!) I did not know about this web site until today.
I hope to find others who are also Teash's or Strehlows!
