Seventeen Penarth RFC players were killed during the war and are commemorated by the Memorial Stand above the clubhouse's Long Room.

[4] A number of Penarth RFC players have achieved international caps for Wales and the British Lions, between the late 1880s and the early 1960s.

Brothers Len and John Dyke were toured New Zealand with the 1908 Anglo-Welsh team, joined by former Penarth captain Reggie Gibbs.

Other Penarth players gaining Welsh international caps were Mel Rosser (1924), Jack Bassett (1929–1932), Gomer Hughes (1934) and Frank Trott (1939-1945).

During the course of the year a number of special games were played, including fixtures against the Glamorgan County, Welsh Academicals, and Coal Island Éire sides.

Also that year former Wales rugby Captain Hemi Taylor, a playing member of Penarth RFC senior team, presented the club's highly successful youth section with a cheque for £1,500 on behalf of the ‘Bears Golf Society'.
