Beauclerk (1773-1850) was the fourth son of Aubrey Beauclerk, fifth Duke of St Albans, and a direct descendant of Charles II and Nell Gwyn. He was educated at Eton and Trinity College, Cambridge, took holy orders, and held the living of St Michael's, Bromley-by-Bow, and later the rectory of Kimpton in Hertfordshire. His parishioners scarcely saw him; the cricket fields of Lord's saw him almost every day from late spring to early autumn. By 1810 he was already the leading amateur batsman in England — a right-hander with a careful, professional technique by the standards of the day — and a slow underarm bowler of unusual accuracy who could lift the ball off a length to threaten the gloves of the wicketkeeper. He was also an unrepentant gambler. William Denison estimated his cricket winnings at 600 guineas a year through the 1810s, a sum equivalent to perhaps £50,000 today. Through the war years he kept senior cricket alive almost single-handedly, captaining one of the elevens in each of the three recorded matches of 1811-13 and resuming senior fixtures from 1814. He played in the inaugural Gentlemen v Players matches of 1806, in the Eton-Harrow series, and in the resumed Gentlemen v Players match of 1819. He was also the most powerful figure on the MCC committee from about 1815 onwards, using his influence to ban William Lambert in 1817 and George Osbaldeston in 1818, both following private quarrels. His temper was famous: contemporaries reported him swearing audibly at fielders and umpires, in language unbecoming of any clergyman and especially of one whose family motto was 'God protect us'. He played his last senior match in 1825 and continued as an MCC committeeman until his death.
