Herman Charles Kunkle was father to my maternal grandfather Robert H.C. (Herman Charles) Kunkle, but abandoned the family and my grandfather refused to investigate his whereabouts thereafter. I have some possible information--he may have started a family in Allegheny County, PA. Census records point to this IF in fact it is the same Herman Kunkle He seemed to have two more children by the 1940 census (in addition to the two from his first marriage to Helen Amanda Strause Kunkle).
