Baron Kerry is an ancient title in the Peerage of Ireland, named after County Kerry.
There are differing accounts as to which FitzMaurice was the 1st Baron Kerry. The Complete Peerage starts the numbering at Maurice Fitzthomas.
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.
