Elizabeth Jaquelin Ambler Brent Carrington also known as Betsy Ambler Carrington (March 11, 1765–February 15, 1842) founded the Female Humane Association in Richmond, Virginia. It is now known as the Memorial Foundation for Children. Believed to be the first of its kind in Virginia, the organization provided safety and shelter to destitute girls and kept they from a life of poverty and the possibility of becoming prostitutes to survive.
She corresponded with friends and family over the course of her life and her letters and papers are held at the Library of Congress, Mount Vernon, Colonial Williamsburg Foundation, and the University of Virginia. In them, she describes her life as a child, her short-lived marriage to William Brent, who died suddenly months after their marriage, and her second husband Edward Carrington. She corresponded with and wrote about Chief Justice John Marshall, George and Martha Washington, her sisters, and other friends and relatives.
