One of the first branches of the South End House was here at 20 Union Park. It began as a men’s residence in 1901, and later became a service center until 1959. Beatrice Williams (1898–1986) lived and served the community in this South End House residence for twenty-five years. She represented the South End on many city commissions. She began her life-time of service in 1920 when she worked in France as a member of the American Committee for Devastated France helping with the restoration of twenty-six villages in northern France destroyed during the first World War.
