Sophia Kasten Pribbenow

My Great grandmother Sophia Kasten born in Hanover, Germany{ Hildesheim} Came to Wisconsin, Kilbourne in 1870`s or late 1860`s married John WILLIAM Pribbenow. Both buried in Wisconsin Dells. Her Father died in her early childhood. Her Mother remarried Mr. Schlicter sp?. Sophia had a full brother & many Half siblings. I think she came to U.S. with her Kasten brother. Any info VERY HELPFUL. Thank you Muriel
