Looking for information on my gg grandmother Anna Bertha Wilhelm, born Oct. 1979 in Germany. Immigrated to the US in 1881. She had a sister Josephine Wilhelm, born in the US in 1886. Anna married Joseph F. Hoyer, born 1876?in Germany?. The 1900,1920 and 1930 census show them in Chicago, Illinois. Joesphine was living with Anna and husband in 1900 and was 14 years old. Anna died in 1959 and is buried in Mount Hope Cemetery. Any info about Anna's parents would be appreciated.
