Claes Maartenszen van Rosenvelt (c. 1626–1659), the immigrant ancestor of the Roosevelt family, arrived in New Amsterdam (present-day New York City) sometime between 1638 and 1649.

About the year 1652, he bought a farm from Lambert van Valckenburgh, comprising 24 morgens (i.e., 20.44 ha or 50.51 acres) in what is now Midtown Manhattan, including the present site of the Empire State Building.

Despite political differences that caused family members to actively campaign against each other, the two branches generally remained friendly.

A traditional blazon suggested would be, Per fess vert a chevron between three roses argent and Or a lion rampant gules.

[3] The coat of arms of the namesakes of the Dutch immigrant Claes van Rosenvelt, ancestor of the American political family that included Theodore and Franklin D. Roosevelt, was white with a rosebush with three rose flowers growing upon a grassy mound, the crest being of three ostrich feathers divided into red and white halves each.
