After her death in 1944, she bequeathed $2,000 to the Town for a fund to aid needy and deserving girls in pursuit of education. The East Lexington branch library which had been established in 1883, occupied it until the building was closed for repairs in 2007.In 1945 a demolition permit was issued for the building followed by several attempts to find a new site on which to locate it.
