Roggerman or Roggeman or Roggermann? In U.S. census forms, the name is listed as either Roggerman or Roggeman. With the exception of Charles' youngest child, George who chose to use the name Roggeman without the "r", the rest of the family regularly used Roggerman. In some German records it is spelled Roggermann and that is how it appears on the headstone for Charles, the ancestor who came from Germany although he used Roggerman during his life in America... from what we can tell.
