In 1325, Maurice FitzMaurice, 4th Baron Kerry, murdered Diarmaid Óg MacCarthy (son of Cormac Mór MacCarthy) in the courtroom at Tralee. For this act, Maurice was tried and attainted by the parliament in Dublin and his lands forfeited, but after his death they were restored to his brother John FitzMaurice, 5th Baron of Kerry.
The title was sometimes given as Baron Lixnaw (after Lixnaw) or Baron Kerry and Lixnaw. In a 1615 dispute with Baron Slane over precedence, it was claimed the title "Baron Lixnaw" was promoted by the rival Earl of Desmond, who wanted "Baron Kerry" to be a a courtesy title for his heir. The Privy Council of Ireland's ruling in the dispute referred to Baron Kerry as both "Lo[rd] of Kierry" and "Baron of Kierry and Licksnawe" [sic].
In 1537, the eleventh Baron was created Baron Odorney and Viscount Kilmaule in the Peerage of Ireland. However, these titles became extinct on his death in 1541 while he was succeeded in the Barony of Kerry by his younger brother.
The twenty-first Baron was created Earl of Kerry in the Peerage of Ireland in 1723. His younger son John Petty Fitzmaurice was created the 1st Earl of Shelbourne in the Peerage of Ireland in 1753 and his son William Petty FitzMaurice, the 2nd Earl of Shelburne, who served as British prime minister from 1782 to 1783, was created Marquess of Lansdowne in 1784. In 1818 the latter's son, the third Marquess, succeeded his cousin as 4th Earl of Kerry and 24th Baron Kerry. Earl of Kerry has subsequently been used as a courtesy title by heirs of the Marquess.
