My Grandmother was born in 1927 in Wauwatosa. Her birth name was Irene Knoch, daughter of unwed mother Anna Knoth or Knoch. Anna was born in Yugoslovia or came from Croatia/Hungary and was 17 years old at the time of my grandmother's birth and had 2 children prior. My Grandmother was placed with the Milwaukee Home for Dependent Children and later adopted at the age of 1 by Edward and Milda Schopf. Her adoptive name was Gertrude Schopf. Trying to find information on the mother Anna or birth father and the 2 other children.
