Jost Rifenburgh-20, Jost Reiffenberger-30 and Jost Reiffenberg-44 all born 1495 in Germany are the same person (in spite of one death date being different). They should all be merged and the surname changed to Reifenberg as the preferred, with the other variations noted. The name of the village, knights and castle is Reifenberg. I have been researching the surname and history of the knights von Reifenberg because it is the original spelling of my surname. There are living Reifenberg descendants in the same area of Germany who have trees going back even farther. I have history books with the name connected to the area. I learned some German and bought 3 books which contain information about the surname, knights and castle connected to Oberreifenberg, in the Taunus Mountains outside Frankfurt, Hesse, Germany. NOTE: I edited my question to numbers -20, -30 and -44. Jost Reiffenberger-28 and Jost Reifenberg-1 are a separate problem.
