In the early thirties Ballycastle GAA player, Tom Grier, was rated one of the best club footballers in the country. He won an array of medals and awards.

He was captain of the Mayo Junior team that won the All-Ireland in 1933. He won two National League Medals in 1933 and 1934 and an All-Ireland Medal in 1936 as a member of the first Mayo team to win the Sam Maguire Cup.

In 1935 he was captain of Ballycastle's Intermediate team that won the County Championship. The following year he captained Ballycastle's Senior Team that won their first County Senior title. He led Ballycastle Senior Team again in 1937 to the County Final.

The county minute book recalls the '37 Final as not having taken place between Castlebar and Ballycastle due to a misunderstanding with the Ballycastle Club. He was captain again in 1939 and Ballycastle won the County Final and Tom won his third County Senior Medal.

The clubhouse in Tom Langan Park, which was erected in 1994, is named in his honour.
