        "I tell you, Kermit, it was great comfort to feel,
        all during the last days when affairs looked doubtful,
        that no matter how things came out the really
        important thing was the lovely life I have with
        Mother and with you children, and that compared
        to this home life everything else was of very
        small importance from the standpoint of happiness."

                   - Theodore Roosevelt, letter to Kermit, 10 November 1904

Origins of The Roosevelt Family

In 1410, William III, Duke of Bavaria, Count of Holland and of Zeeland granted lands (amt fiefdoms) north of Tholen
to six vassal lords; amongst them was Marijnus van Rosevelt of the Oud-Vossemeer House of Amt Lords,
whose primary ancestral residence was eventually built in 1767.

Claes Maartenszen van Rosenvelt of the Oud-Vossemeer House of Amt Lords emigrated to New Amsterdam,
present day New York City, sometime between 1638 and 1649. Around 1652, Claes bought a 48 acre farm from
Lambert van Valckenburgh in present-day midtown Manhattan. In present geographical terms,
the property emcompassed everything surrounded by a square created by the intersections of
Lexington & Fifth Avenues and 29th St. & 35th St.

Claes' son Nicholas changed the spelling of the family name to Roosevelt. Nicholas was also the first Roosevelt to
hold political office as an alderman. Nicholas' children, Johannes and Jacobus, became the respective patriarchs
of the Oyster Bay and Hyde Park branches of the Roosevelt family.
