A native of New Jersey, Thomas Fraser sided with the Crown at the outbreak of the American Revolution. Fraser received a lieutenant's commission and served in the Loyalist unit, the New York Volunteers. Wounded at Musgrove Mill in August 1780, Fraser received a promotion to major for this service. Fraser elected to remain in South Carolina following the British evacuation of Charleston in December 1782. He lived along the Edisto River and eventually became a commission merchant in Charleston.
