In 1948 a championship cup was procured and was named in honor of Richard Gummere, a longtime teacher and coach at both Browne & Nichols and Haverford College; the Gummere Cup is undoubtedly one of the oldest secondary school soccer trophies in the country. In 1968 Middlesex joined the group and in 1971 Roxbury Latin competed before joining permanently in 1974. 1972 saw Tabor leave the league and Groton join. That brought the league to ten schools where it remained until 1984.
