The house at 27 Main Street in Farmington was built for Samuel Smith in 1769. It was later the home of Horace Cowles (1782-1841) and his wife Mary Ann (1784-1837). In the years before the Civil War, they were stationmasters on the Underground Railroad who his fugitive slaves in their home. One day they had to go out and they left their young daughter, Mary Ann (1826-1899), in charge. She sat at the front door all day long and refused to let anyone enter, including a slave catcher from the South who had to leave empty handed. One of the three Mende girls from the Amistad stayed with the Cowles family when the captives from that ship were staying in Farmington. After Cowles died, his son, Samuel Smith Cowles inherited the house and continued his father’s work aiding fugitive slaves. He also edited an anti-slavery newspaper, The Charter Oak. Samuel Smith Cowles also became Treasurer of the Farmington Savings Bank.
