My Mom Leah Davidson Harris said that her "aunt" Louise Schneider came to stay with the Davidsons in Oswego, Clackamas, Oregon in the 1920s to help care for them as there was a disease going around. It wasn't the famous flu though. Later Louise and husband Herman moved back to McCook, Nebraska. a 1920s census shows the Schneiders in Oswego. After looking at several family letters and notes it appears that Louise (born 1865-1866 in Germany and immigrated in 1884)and Auguste Rosentreter were sisters. Notes say Auguste was a Bluwernick and her mother and sisters were name of Weidemann. Their mother evidently married twice. But Louise is shown with surname of Rosenthal in her marriage record on family search, date was 11 Nov 1886 in Detroit, Michigan. Louise was 20 and Herman was 35. Louise's sister Mary Weidemann was married to Heinrich Schneider, brother to Herman, they can be found living next to or together on a census, perhaps in Nebraska. The Poznan Project has a marriage in Margonin in 1854 for a Johann Bluwernick, age 26y 2m, and Johanna Louise Kemnitz, age 22 y 3m. These could be Auguste's parents. I'm still confused with all these names.
