About Isaac Roosevelt

Isaac Daniel Roosevelt (September 29, 1790 – December 24, 1863) was an American medical doctor and farmer. He was the paternal grandfather of U.S. President Franklin D. Roosevelt.
Early life Roosevelt was born on September 29, 1790, in New York City, he was the oldest surviving son of businessman and politician James Roosevelt (1760–1847) and Maria Eliza Walton (1769–1810), the daughter of Admiral Gerard Walton (d. 1821) and a descendant of Wilhelmus Beekman, who was the treasurer of the Dutch West India Company, Mayor of New York City, Governor of Delaware from 1653 to 1664, and Governor of Pennsylvania from 1658 to 1663.
His paternal grandparents were merchant and politician Isaac Roosevelt (1726–1794), a New York State Assemblyman and member of the New York State Constitutional Convention, and Cornelia Hoffman. He was the 3x-great-grandson of the first Roosevelt in America, Claes Maartenszen Van Rosenvelt (d. 1659). He continued his medical studies until 1820 with Dr. David Hosack.
Instead, Roosevelt's passions were with farming and when his father purchased Mount Hope, a large tract of land in Hyde Park, New York, along the Hudson River, Roosevelt left New York City to live there permanently.
Personal life In 1825, he married Mary Rebecca Aspinwall (1809–1886), daughter of merchant John Aspinwall (1779–1847) and Susan ( Howland) Aspinwall (1779–1852) of New York.
He died on December 24, 1863, at the age of 73 in Hyde Park, New York. His elder son, James, inherited Mount Hope (which burnt down in 1866 and the land was sold to the state of New York after which he purchased Springwood in Hyde Park), and his younger son, John, inherited Rosedale.
