Sir Robert Booth (1626–1681) was an English-born judge who had a highly successful career in Ireland, where he held the offices of Chief Justice of the Irish Common Pleas and Lord Chief Justice of the King's Bench in Ireland. Early life He belonged to the wealthy Booth family of Salford: he was the eldest son of Robert Booth, a wealthy landowner, and Anne Mosley, daughter of Oswald Mosley of Ancoats, Manchester, (who was also the ancestor of the prominent twentieth-century politician Sir Oswald Mosley), and his wife Anne Lowe. His father died when Robert was about twelve and his mother remarried the noted Presbyterian preacher and Parliamentarian Thomas Case. Booth himself, though he was a member of the Church of England, had strong nonconformist leanings. He was educated at Manchester Grammar School and St. John's College, Cambridge, where he matriculated in 1644. He entered Gray's Inn in 1642 and was called to the bar in 1650; he became an ancient of Gray's Inn in 1662. Career He is first heard of in Ireland in the entourage of William Steele, the Lord Chancellor of Ireland, in 1657, and entered the King's Inns the same year. After the Restoration he had the good fortune to attract the notice of Steele's successor, Sir Maurice Eustace. Eustace, a staunch Royalist, was normally hostile to anyone who had been associated with the Cromwellian regime (although he had made his peace with it himself), but he admired Booth's legal ability and believed (perhaps naively) that his wealth would preserve him from corruption. That Booth's stepfather Thomas Case, though a staunch Presbyterian, has strongly supported the Restoration may also have been a recommendation. Booth was appointed a puisne justice of the Court of Common Pleas (Ireland) in 1660 and its Chief Justice in 1670, by which time he had already begun to suffer from the chronic ill-health which plagued his later years. His salary was fixed at £300 a year. He was a Bencher of the King's Inns and lived conveniently close to the Inns on present-day Church Street. He was one of the original Governors of the Erasmus Smith schools. He regularly visited England to consult with his medical advisers, and was knighted while on a trip to England in 1668. He was passed over as Lord Chief Justice when the office fell vacant in 1673, on account of his strong Protestant sympathies. Lord Chief Justice
