Deroy Park is owned by the city. Deroy Park was once called Canochet Park. Deroy Park is named after Narcisse Amedee Deroy who died during World War 1. Narcisse Deroy had a brother on the city council of Holyoke for 25 years and I believe that he helped have the park named for Narcisse. (Narcisse Deroy is my grandmother’s second cousin.) The park was renamed July 20, 1941. FINDAGRAVE
