A number of Penarth RFC players have achieved international caps for Wales and the British Lions, between the late 1880s and the early 1960s. These included Richard Garrett (1888 – 1892), George Rowles (1892) and John M C Dyke (1906). Brothers Len and John Dyke were toured New Zealand with the 1908 Anglo-Welsh team, joined by former Penarth captain Reggie Gibbs.
