Augusta (Burow) Scherffius, who lived in Blackhawk County, IA, was my great-grandfather's sister. They came to the US in 1866 from Prussia when she was 16 and settled in Sauk Center, MN. I don't know anything about her husband, but when my great-grandfather died in 1935, she was living in Cedar Falls, IA. The Burows did have relatives (surname Knebel) that went from MN to TX, with Waco, Galveston, and Austin mentioned.
