In 1870, Nathaniel Hayden (1835-1916), a Civil War veteran, moved to a house (now the Ahern Funeral Home) on Main Street in Unionville in Farmington. He had served as a captain in the 16th Connecticut and was wounded at the Battle of Antietam. He would later be the primary donor for Unionville’s Civil War monument, dying just weeks after it was dedicated on July 15, 1916. Hayden’s original next-door neighbor was a tableware manufacturer named Russell Humphrey. In June of 1875, Humphrey’s widow Aurelia sold Hayden a tract of land at the rear of her property, along what is now Maple Avenue. Hayden then constructed a tenement building on the property, which would have housed workers at the nearby paper mills. Title to the building passed to Ernest M. and Ida A. Hart in 1916. The apartment building still exists at 52-56 Maple Avenue and represents a period of industrialization in Unionville.
