Career
Born in Trealaw, Ballsom joined Gillingham in 1935 from Tunbridge Wells Rangers and went on to make 45 appearances for the club in The Football League. When the club was voted out of the league in 1938, however, he returned to his native Wales and signed for Cardiff City. Taking over from Arthur Granville, Ballsom played in 34 league games for the club during the 1938-1939 season and was retained for the following year but the outbreak of World World War II meant he did not feature for the club again.
