Geoffrey Osbaldeston

Geoffrey Osbaldeston (1558-c.1635) was an English-born politician and judge who had a long but rather undistinguished career in Ireland.

He was the third son of Edward Osbaldeston of Osbaldeston Hall, a member of an old and prominent Lancashire family, and Maud, daughter of Sir Thomas Halsall. The Osbaldestons were related to the Stanleys, Earls of Derby, and Edward seems to have owed his success to their patronage. Edward Osbaldeston, the Roman Catholic martyr, was his first cousin. He was educated at St Mary Hall, Oxford and entered Gray's Inn in 1577, becoming an Ancient of the Inn (a senior rank, though junior to Reader) in 1593.

Portrait tentatively identified as Alice, Countess of Derby, by an unknown artist. Geoffrey owed much to her patronage. In 1601 Alice, Countess of Derby, who acted as his patroness, lobbied on his behalf to obtain an official position for him in Ireland. Unfortunately for Osbaldeston's future career prospects the Lord Deputy of Ireland, Sir Arthur Chichester, soon formed a very poor view of his efficiency, a step which was generally seen as a demotion on the ground of his professional incompetence. his precise date of death does not seem to be recorded.

He married Lucy (or Louisa) Warren, youngest daughter of John Warren of Poynton in Cheshire and his wife Margaret Molyneux and had three children. Through his daughter Deborah he was the ancestor of the prominent Lyster family of County Roscommon. Richard Osbaldeston, Attorney General for Ireland, was a cousin of Geoffrey's of the next generation.
