[2][3] In the early part of the 20th century, many Roman Catholic churches started schools to educate children of their parish.

In the fall of 1947, the parish high schools of Holy Rosary, Sacred Heart, and St. Jerome played sports for the first time under the banner of Holyoke Catholic.

Despite the moves to Granby and Chicopee, the school still used St. Jerome Parish in Holyoke for its commencement ceremonies.
