John Burnell
John Burnell was an Irish judge who held office as Chief Baron of the Irish Exchequer.
The Burnell family had been Lords of the Manor of Balgriffin, County Dublin since the fourteenth century: they acquired the manor of Castleknock through marriage into the Tyrrell family, who held the feudal barony of Castleknock. The family had a strong
tradition of judicial service; Robert Burnell, who was probably John's great- grandfather, and who married the Tyrrell heiress to Castleknock, was a Baron of the Court of Exchequer 1388–1413, as was John's cousin Patrick Burnell . The family tradition of judicial service was continued by Henry Burnell, who was Recorder of Dublin and a judge of the Court of King's Bench.
John was made a Baron of the Court of Exchequer for life in 1478. In 1482 he was appointed Deputy to the Chief Baron of the Irish Exchequer, Oliver FitzEustace. Elrington Ball explains that a Deputy was required because Oliver was considered to be mentally deficient, and was unable to speak or apparently understand what was said to him, so that the oath of office could not be administered to him. Oliver was a natural son of the powerful Irish nobleman Rowland FitzEustace, 1st Baron Portlester, who obtained the position of Chief Baron for his son and the right to name a Deputy Chief Baron for himself. Burnell was superseded as Deputy in 1487. In 1491 he and Oliver were appointed joint Chief Barons, presumably due to Portlester's influence, but Burnell seems to have died soon afterwards.
