Named for two of its early-19th-century notable owners, Parson Mason Locke Weems and attorney Benjamin Botts, the museum interprets the era in which they lived, when Dumfries was a major port and commercial center. Parson Mason Locke Weems, an Episcopal minister, is best known for his biography of George Washington and his story of the boy and barking his father’s cherry tree. Weems owned the house briefly and operated a bookstore there. Benjamin Botts was a member of Aaron Burr’s defense team when the former vice president was tried for treason but acquitted in 1807. The Merchant family owned the house from 1869 to 1968 and is said to haunt the place now.
