I was doing some research myself on my family(Schutte) who live in Mapleton,MN. I found that name Anna E. Rabenhorst was sister to Amelia Rabenhorst 1859-1953 who married my great grandfather Herman C. Schutte 1855-1951. They came from Germany about 1881 and had 8 children,one of which was my grandfather Herman Albert Schutte b.11-15-1888,d.march 1986. Anna appears to have had brothers John,Herman,Carl,and sisters Augusta,Amelia,and Marie. From what I found,John married an Amelia,they had a son John who married Alma Detjen,they had a son Edgar John Henry Rabenhorst who was one of our neighbors. I have more info on some of the rabenhorsts in the Mapleton area also.
