John Osborne (barrister)

John Osborne (c.1630-1692) was an English barrister and judge, who spent much of his life in Ireland. He was the only son of the celebrated writer Francis Osborne, and was the subject of his father's most famous book, Advice to a Son (1656-1658).

John qualified as a barrister and moved to Ireland where he rose to the top of the legal profession. He became Prime Serjeant-at-law under King Charles II. Since he was a determined opponent of King James II, he was removed from office by James's government, and was later proscribed by the Irish Parliament. After the Glorious Revolution he was restored to office as Serjeant. His notable independence of mind, and his detestation of all former Jacobites, Protestant as well as Roman Catholic, which extended even to those who had pledged their loyalty to the new King William III, soon made him almost as obnoxious to the new regime as he had been to the old. He was dismissed from office shortly before his death in 1692.

His father Francis Osborne was the fifth son of Sir John Osborne of Chicksands Priory, Shefford, Bedfordshire and his wife Dorothy Barlee of Effingham Hall, Essex; Peter Osborne, Royal Governor of Guernsey during the English Civil War, was Francis's elder brother.

Francis Osborne married Anna Draper, sister of the prominent Parliamentarian Colonel William Draper: John was the only boy of their four surviving children. Francis shared his brother-in-law's political beliefs, although he played little part in public life. His celebrated book Advice to a Son, which he intended for John's education, was published in two volumes in 1656 and 1658. He moved to Oxford to be closer to his son, and died there in 1659.
