Harry S. Truman - Treumann von Ruegen

Hallo to all listener,

some times ago I read in one of these lists about Harry S. Truman, president of
the United States. His ancestors named TREUMANN (=Truman) came from Germany from
the Ruegen Island.

Know I am doing family search for a German Familiy Treumann, coming from Ruegen
too. They are very interested in this connection.

Is there anybody in this list, who can help to find or to tell me some links
or book titles to find further information about the family tree of Harry S.
Truman??

I would very much appreciate every answer in this matter.

Best regards from Germany
