Clapham Rovers  was formed on 10 August 1869 initially playing under both codes, with Association rules to be played one week, and Rugby the other. This peculiar feature in the constitution of the club obtained for the club the sobriquet of the "Hybrid Club". Clapham Rovers were one of the fifteen teams to play in the very first FA Cup competition, in 1871–72.  The Club reached the FA Cup Final in 1878-79 but lost 1-0 to Old Etonians. . In this match, Clapham Rovers' James Prinsep set a record for being the youngest player in an FA Cup Final, at 17 years and 245 days, a record that held until 2004 when it was broken by Millwall's Curtis Weston.  They reached the final again the following year and this time lifted the trophy after a 1–0 win over Oxford University at The Kennington Oval.  Clapham Rovers were also one of ten founder members of the Surrey County Football Association, in 1877.  During the 1870s they were also successful at rugby boasting four international players.  The date of the club's dissolution is unclear, although the last time they competed in the FA Cup was in the 1885–86 season, when they were disqualified without playing a match.The club probably survived until World War I as there is a reference to their annual dinner in The Sportsman in 1911.
