In 1763 Theodosia Bartow married James Marcus Prevost, a British Army officer with whom she had five children. They lived in Bergen County, New Jersey, in a home they named the Hermitage. In 1776 James Marcus was called back to active duty in the Revolutionary War, while Theodosia tried to keep their home from being confiscated by the American government. Meanwhile, she began a relationship with a young American officer named Aaron Burr. After her husband’s death in 1781, 35-year-old Theodosia Prevost, with five children, married 25-year-old Aaron Burr. Theodosius Bartow died in a carriage accident in Shrewsbury, New Jersey, in 1746 at age 34, while his wife Ann was pregnant with their only child, Theodosia Bartow. For five years Ann raised Theodosia as a single parent, apparently partially in Shrewsbury and partially in New York City where several of her sisters and brothers were living. Since two of Ann’s sisters had recently married men with military backgrounds, and Ann met and married British Captain Philip De Visme in 1751. Ann had five children with Philip between 1752 and 1768, half brothers and sisters to Theodosia. Philip died in 1768, and Ann at 49 was again a widow, now with six children. Theodosia was then 16. There is no record that Theodosia had any extensive schooling, but her knowledge of languages, her analytic abilities, and her reading habits indicate that she was educated at home, far more extensively than most privileged women in the colonial New York area.
