I think I have the answer to your puzzle. I am researching my maternal grandfather's family by the name Roher. I have an obituary about Francis Roher who was my ggrandfather's brother. In it there is mention that Francis is the son of John and Mary Munson Roher. It also says that he is survived by a brother, Clarence Roher, and a sister, Flora Williams of IL. In the 1880 Census, there are twins listed as Flora and Nora. In the 1900 Census, it shows that they had 9 children with 8 living. I do so hope this is what you are looking for. If it is, I can give you more details.
