County Kilkenny was created after the
Norman invasion of Ireland from most of the Gaelic
Kingdom of Ossory. From 1328, the
Anglo-Norman Butler Earl of Ormond had
palatine jurisdiction over the neighbouring county of
Tipperary, and in the 15th century, the Butlers extended this de facto to most of Kilkenny. This was reflected in the subsidiary title
Earl of Ossory which
Piers Butler, 8th Earl of Ormond was granted in 1538. However, in the 14th and 15th centuries, the
Gaelic Fitzpatrick family () encroached southwards into Kilkenny and ruled as "Lords of Upper Ossory". In 1541, during the
Tudor reconquest of Ireland,
Barnaby Fitzpatrick () was created 1st
Baron Upper Ossory upon the
surrender and regrant of his lands to and by
Henry VIII, legitimating his lordship in the eyes of the
Dublin Castle administration. Queen's County
was created in 1556 from unshired lands northeast of Upper Ossory. In 1575,
Henry Sidney, then
Lord Deputy of Ireland, wrote "Upper Osserie is so well governed and defended, by the valor and wisedome of the Baron that nowe is as ... it made no matter, if the countrie were never shired, ... and yet united to some shire it shal be". Fitzpatrick preferred to be subject to the
new English planters in Queen's County rather than his Ormond enemies in Kilkenny. By
letters patent of 21 July 1600 Upper Ossory was formally transferred to Queen's County. An exception was made for an area around
Durrow, which remained an
exclave of the Kilkenny
barony of Galmoy. After
Arthur Chichester was made Lord Deputy in 1605, the lordship of the Fitzpatricks effectively ended. A 1621
inquisition in Maryborough (now
Portlaoise) ruled that the king,
James I, was lord of Upper Ossory, and he proceeded to grant
George Villiers, 1st Duke of Buckingham extensive lands in the barony. ==Supersession==
