Baron Lisle

Baron Lisle was a title that was created five times in the Peerage of England during the Middle Ages and Tudor period. The earliest creation was for the family of Lisle of Rougemont, which bore arms: Or, a fess between two chevrons sable. The later creation of 1357 was for Lisle of Kingston Lisle, a younger branch of the Lisles of Rougemont. Robert de Lisle of Rougemont married Alice FitzGerold (granddaughter of Henry I FitzGerold (d.1173/4)), the heiress of Kingston in the parish of Sparsholt, Berkshire. In 1269 Alice granted the manor of Kingston to her younger son Gerard I de Lisle, whose family adopted the arms of FitzGerold: Gules, a lion statant guardant argent crowned or. Gerard I's grandson was Gerard II de Lisle (1305–1360), created Baron Lisle in 1357.

The most recent creation came in the Peerage of Ireland in 1758, when John Lysaght was made Baron Lisle, of Mountnorth in the County of Cork. He had previously represented Charleville in the Irish House of Commons. As of 2013 the title is held by his great-great-great-great-great-great-grandson, the ninth Baron, who succeeded his father in 2003. The barony is pronounced "Lyle", the family surname of Lysaght "Lycett".
