Coles Mills was one of the first settlements in the Southern Precinct of Dutchess County, now Putnam County, in the U.S. State of New York. Cole's Mills features prominently on the 19th Century maps of the area including the 1854 R. F. O’Connor Map of Putnam County,[1] the 1867 F.W. Beers Map,[2] and the United States Geological Survey map from 1892.[3]
