The first Garndiffaith Rugby side was formed in 1922 and their fixtures then consisted of sides like Caerleon College, Llanhilleth All Blacks and Pontypool Quins (who later became Pontypool United RFC) . All were respected sides in the Monmouthshire area and during these early years the Garn side were winning more games than they were losing. Gardiffaith's home record occurred in the mid-1920s to the mid-1930s when the club went without being defeated at home for nine seasons. That level of performance attracted a large following of supporters but the record finally broke when Pontypool Quins visited the Garn and won by 3 points to nil.
