Which Roman Catholic monarch of England, Scotland, and Ireland appointed Sir Brian O'Neill as judge?
Sir Brian O'Neill, 2nd Baronet Sir Brian O'Neill, 2nd Baronet (died 1694) was an Irish landowner, barrister  and judge. He was one of the Roman Catholic judges appointed by James II of England in his efforts to "Romanise" the Irish administration. As such he and his fellow Catholic judges have been treated harshly by historians. However William of Orange, after he overthrew his father-in-law James II, also made use of O'Neill's services for a time. He was the second of the O'Neill Baronets of Upper Claneboys.
Edward VI of England Edward VI (12 October 1537 – 6 July 1553) was King of England and Ireland from 28 January 1547 until his death. He was crowned on 20 February at the age of nine. The son of Henry VIII and Jane Seymour, Edward was England's first monarch to be raised as a Protestant. During his reign, the realm was governed by a Regency Council because he never reached his majority. The Council was first led by his uncle Edward Seymour, 1st Duke of Somerset (1547–1549), and then by John Dudley, 1st Earl of Warwick, from 1551 Duke of Northumberland.
