I have no way of knowing if the Lowe's Rehfelt are related to the Refelldts from Hamburg, Germany. My mother believes they were bombed during WWII and our family lost contact with them. I don't think they were from Prussia. Only thing I know is that my grandmother mentioned in her 1926 trip, diary she met Rehfeldt's cousins in Hamburg. She took street car and walked so they must have lived in the city near the tracks.
