Baron Alington was a title that was created three times in British history. The first creation came in the Peerage of Ireland on 28 July 1642 when William Alington was made Baron Alington, of Killard in the County of Cork. His second son, the third Baron (who succeeded in the title on the early death of his elder brother), was a Major-General in the English Army. On 5 December 1682 he was created Baron Alington, of Wymondley in the County of Hertford, in the Peerage of England. The English barony became extinct on the death of his young son Giles, the fourth Baron, in 1691. The late Baron was succeeded in the Irish barony by his uncle, the fifth Baron. He was a captain in the army. On his death in February 1723 the Irish barony became extinct as well.
