He married Pauline Anne Hogan on 12 November 1952.

Twomey mainly played across the centreline or on a flank and started as a winger.

He was tough, fast, and was a tireless contributor in his appearances for Collingwood, with a long driving left-foot kick and a good mark.

He was on the half-forward flank, his older brother, Bill, was the centre, and his younger brother, Mick, was second ruck, resting in the forward pocket.
