The house at 74 Windham Street in Willimantic was built for Mary B. Clark in 1896, four years after the town selectmen voted to extend Windham Street north from Valley Street, opening lots near the new Willimantic Normal School. Born in 1844 in Coventry, Mary Bidwell Winchester was the niece of the founder of the Smith and Winchester Company, paper manufacturers in South Windham. She married and later divorced Daniel S. Clark Jr., a machinist who was five years her junior. After the divorce, Mary Clark became wealthy investing in real estate, however in late 1905 her behavior was becoming erratic. She became terrified her house would be burgled while she slept. She kept the lights on all night and fired her revolver at sheets on the close-line outside that she believed might be potential burglars. When the police arrived to investigate, they were threatened with a “dose of lead.” Mrs. Clark was arrested for discharging firearms in the city limits. She was eventually taken to the Hartford Retreat for the Insane, where she remained until her death in 1929 at the age of 84.
There is an interesting article detailing the history of the house: Part One|Part Two|Part Three.
