Upon Isabel Herdle's death in 2004 at age 99, the MAG inherited most of her estate, consisting of the contents of her longtime Pittsford home. The MAG kept papers that related to their institution and transferred what became the Herdle Family Papers in November 2005. The papers include numerous photographs of the Herdle, Bachman, and Miller families, as well as material related to Gertrude's interest in tombstones as American folk art.

Mostly official correspondence from Wood’s work as curator of the American Numismatic Society.
