Rosemary C. Weiterman (Fischer) - Rosemary Weiterman (Adopted name Fischer)

My Mother was adopted by Joseph F. Fischer and Mary P. Fischer(Schlagenhaft) in 1930 after the death of Alice Fischer in 1929, the only child of Joseph and Mary. I have no further information on the adoption of my Mother Rosemary, or any information regarding my Mother and the circumstances of her adoption. My Mother believed to be born in Milwaukee WI, but records were destroyed.
Any information would be helpful in our search.
