Who?

This photo shows the Ballyfermot team that won the national Community Games championship in 1970. (Click on the picture for a larger version.)

One player in this picture (call him Player A) was later a Leinster champion. He’s still playing, and in fact he’s playing in this year’s Armstrong Cup. Who is he?

Another player in the picture (call him Player B) came from a chess-playing family, was one of a pair of brothers on the same Glorney Cup team and was on an Armstrong Cup-winning team. Who is he?

The second question is much harder, I think, as Player B hasn’t played in decades.

The photo is shown with permission (for which many thanks), but I won’t give the reference just yet as it would give away some of the solution.
