Betty, dower slave of Custis family

Betty was a slave owned by Martha Washington. She was an expert at textiles and spent much of her time spinning thread, weaving cloth, and tailoring clothes for both the Washingtons and her fellow bondspeople. Betty was a "Dower Negro," that is she belonged to the estate of Martha's first husband Daniel Parke Custis, and after the Washington nuptials in 1759, moved to Mount Vernon with her mistress.
