According to the 1925 Malvern, Mills County census the parents of George Switzer are
Father:George A. Switzer, b. Ohio
Mother: Elizabeth E. Jackson, b.abt 1864,Iowa
The parents of Ruth (wife of George) are:
Father: John Kace,b. Indiana
Mother: Loretta Horning, b.abt 1866, Indiana
It looks like Icie is a second wife because in 1930 there is a step daughter living with George and Icie.
