Letter on the President's Ancestors.
My dear Mr. Slomovitz:
I am grateful to you for your interesting letter of March 4th. I have no idea as to the source of the story which you say came from my old friend, Chase Osborn. All I know about the origin of the Roosevelt family in this country is that all branches bearing the name are apparently descended from Claes Martenssen Van Roosevelt, who came from Holland sometime before 1648—even the year is uncertain. Where he came from in Holland I do not know, nor do I know who his parents were. There was a family of the same name on one of the Dutch Islands and some of the same name living in Holland as lately as thirty or forty years ago, but, frankly, I have never had either the time or the inclination to try to establish the line on the other side of the ocean before they came over here, nearly three hundred years ago.
In the dim distant past they may 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.
Very sincerely yours,
Philip Slomovitz, Esq.,
