I'm looking for information/parents of Peter EROH (b. 1867 PA). He married Martha E. ZERFOSS (b. 1875 PA) before 1896. They had several children: George Daniel, Paul F., Mabel E., Iona M., Ellen L., Sarah, Ruth, Edna, Nora, Luther, Clarence, and either a Sadie M. or a Sydney. In the 1920 census "it" was listed as Sydney (male, age 21). In the 1910 census, "it" was listed as Sadie M. (female, age 11). I would also like some clarification on that issue too, if possible.
