Elizabeth House Trist (ca. 1751-1828), also called Eliza, was the daughter of Mary Stretch House and Samuel House. She was the grandmother of Nicholas Philip Trist, who married Thomas Jefferson’s granddaughter Virginia Jefferson Randolph at Monticello in 1824. Elizabeth Trist is best known today for her journal detailing a trip to Natchez in 1783-84.1
Thomas Jefferson formed an enduring friendship with Eliza Trist when he stayed at her mother’s Philadelphia boardinghouse during service in the Continental Congress in 1782-84. He advised her in recurring financial difficulties, wrote her regularly, persuaded her to move her family to Albemarle County in 1798, and appointed her only child, Hore Browse Trist, port collector for the lower Mississippi River in 1803, upon which she moved with him to New Orleans. Hore Browse Trist died in 1804, and Elizabeth Trist returned to Virginia in 1808. She spent some of her remaining years as an itinerant houseguest at a variety of Albemarle County estates, including Monticello, where she died and is believed to have been buried.2
