Roosevelt was born on January 30, 1882, in the Hudson Valley town of Hyde Park, New York. His father, James Roosevelt, and his mother, Sara Ann Delano, were sixth cousins and both were from wealthy old New York families.

They were of mostly English descent; Roosevelt's great-grandfather, James Roosevelt, was of Dutch ancestry, and his mother's maiden name, Delano, originated with a French Huguenot immigrant of the 17th century.
