I am a direct descendent of Thomas Jefferson through Jefferson's daughter Martha's first child, Anne Cary Bankhead. Her first child, John Warner Bankhead moved his family, along with the Merriweather Lewis and Carter families to vast properties in Missouri. There the Bankheads flourished through three more generations down to my mother Audrey Bankhead Howard. As a girl she did grow up with many things that came with John Warner from Monticello. Among the items were stuffed pheasants given to Jefferson by Lafayette shortly before he died, several counterpanes and a large selection of books. All these things were given to the Jefferson Memorial Library in St. Louis. Some of that collection was retained by a cousin, Katherine Zuber, who has passed away and we do not know where those items have gone? We are wondering if some of the books you are presently thinking are all from the Coolidge collection my be the ones that have come down through the Bankheads?
