John de Grauntsete or Grantsete (or John of Grantchester) (c. 1270 – c. 1350) was an English judge who lived in fourteenth-century Ireland. We know more about him than we do about any other contemporary Irish judge, and from the surviving information we can form some idea of the lifestyle of an Irish judge in his time. He sat in turn in each of the Irish Courts of common law, and uniquely he is known to have appeared in Court as an advocate even after he became a judge.
John Gernoun, or Gernon was an Irish landowner, soldier and judge who held office as Serjeant-at-law (Ireland) and Chief Justice of the Irish Common Pleas. He gave good service to the Crown during the Scottish Invasion of 1315-18, but as a judge, he was accused of injustice.

John Penros or Penrose was a Cornish lawyer and judge who held high office as Lord Chief Justice of Ireland, and subsequently served as a High Court judge in England and Wales.

He later served as a justice in eyre, and then as a justice of the Court of Common Pleas (Ireland). He was a gifted lawyer, but as a judge was accused of acting unjustly. A case he heard in Kilkenny in 1302 can be seen as a precursor of the Kilkenny Witchcraft Trials of 1324, and involved several of the main actors in the Trials.

On the other hand, his loyalty to the Crown during the Scottish Invasion of Ireland in 1315-18 was said to be extremely doubtful, although he was saved from disgrace by his influential connections. He was murdered by Andrew de Bermingham of Athenry in 1317/18, during the last months of the Bruce Invasion, in the course of a private feud, of which little is known.

He was also accused of unduly high-handed behaviour as Escheator, in taking property into the King's hands for insufficient cause. He became a substantial landowner in two Irish counties. He had children, but his descendants seem to have died out within a couple of generations.
