My Grandmother's sister, Anne Jones, married a George Orf about 1905. They had three children , George, Harold and Beatrice. You are right, the family is either Austrian or German. This Orf family is listed in the 1880 Census in South Cass Township, Schuylkill Co. Pa. I believe George was born around 1874.Anne and George are buried in Mt. Peace Cemetery, just outside of Minersville Pa. There are also several families, who spell their name Orff, buried there. Hope this helps.
