::Reading back what I just wrote I started to wonder why  was so interested in that "n". As I mentioned, to the 17th century Dutch that "n" was immaterial: Roosevelt, Rosevelt, Rosenvelt with or without "van" are used interchangebly. So why would  think that that "n" may be important while to the 17th century Dutch it didn't matter one little bit? Google provides the answer to that question: see Stalin,Roosevelt,Eisenhower biographies. That site states that "The first Roosevelt came to America in 1649. His name was Claes Rosenfelt. He was a Jew." This site contains what appears to be Neo-nazi propaganda, and the fact that I cite it in no way means that I underwrite any of that propaganda. I am not suggesting that  underwrites it either. Here is what Franklin Roosevelt said about a possible connection between the Roosevelt family and the Jewish Rosenfelt's: "Where he (=Claes) came from in Holland I do not know, nor do I know who his parents were. . . . In the dim distant past they rnay have been Jews or Catholics or Protestants -what I am more interested in is whether they were good citizens and believers in God; I hope they were both."
