Born and raised in Ballyphehane, Barry first played as a schoolboy in various juvenile competitions with Ballyphehane National School before later lining out as a student at Sullivan's Quay CBS in Cork. After beginning his clerical studies at St Patrick's College in Maynooth, Barry was part of the university's first ever Fitzgibbon Cup team. Maynooth University contested four successive finals during his time there and Barry won successive Fitzgibbon Cup titles in 1973 and as team captain in 1974.[1][2]
Barry's clerical studies confined his sporting career to a degree as he was often only permitted to play during his summer holidays. After losing SHC finals in 1973 and 1975, he was team captain when Glen Rovers beat Blackrock in the 1976 final.[4] Barry also lined out in the finals of 1978 and 1980 when he was home on holidays, however, the Glen was beaten on both occasions.
