Throughout her life, Florence would continue to confront financial difficulties, and by the late 1890s, she found herself alone on the family homestead.
Among the women artists who stayed and painted at Miss Florence's were Matilda Browne and sisters Lydia and Breta Longacre.
Many other American Impressionist painters summered at the colony, in Griswold's house, among them Wilson Irvine, who arrived in 1914.
Old Lyme resident Harry Hoffman helped to save Griswold's house through a fund-raising campaign so that it could be converted into a museum.
Its collection spans fine art, sculpture, works on paper, artist's studio material, toys and dolls, ceramics, furniture, textiles, decorative arts and historic artifacts, and the Lyme Historical Society archives.
