Their home was the Holley House — today the Bush-Holley House — a colonial saltbox built around 1728 on a hill above Cos Cob Harbor where the Mianus River runs out to the Sound. Josephine and Edward Holley ran it as a boarding house, and the students who came to study with Twachtman took rooms there. In 1896 a young painter named Elmer MacRae arrived as one of those students, fell in love with the Holleys' daughter Constant, married her in 1900, and together they kept the boardinghouse going — and the colony alive — for two more decades.
The colony mattered far beyond the village. Twachtman, Weir, and Hassam were among the founders of The Ten American Painters in 1897, the group that carried Impressionism and the new styles across the country, and writers like Willa Cather and Lincoln Steffens stayed at the Holley House as well. For a few remarkable decades, a tiny Connecticut waterfront village sat close to the center of American art. Historians still count Cos Cob among the most important of the early American art colonies, its story set down in Susan Larkin's study, 'The Cos Cob Art Colony: Impressionists on the Connecticut Shore.'
