Thomas Clagett was a Prince George's County slave owner during the Antebellum period. According to Stones and Bones: Cemetery Records of Prince George's County Maryland, his tombstone describes him as "an upright man that feared God." His eldest son, Thomas William, inherited Weston, which is presently owned by his descendants who raise thoroughbred horses there. - Maryland State Archives, 27 April 2005
