Robert Shirley

Sir Robert Shirley, 4th Baronet (1629–1656), royalist conspirator, was the second son of Sir Henry Shirley, 2nd Baronet. Despite the Catholicism of his family, he was raised within the Church of England by his mother. He was admitted to Corpus Christi College, Cambridge, on 12 August 1645. The following year, on the death of his elder brother, Charles, he inherited the baronetcy and also married, against the wishes of his family, Katharine (d. 1672), daughter of Humphrey Okeover, of Okeover, Staffordshire.

Following the death of his uncle the Earl of Essex Shirley inherited half the Devereux property in England and Ireland. An ardent royalist, he confronted soldiers at the parliamentary garrison at Ashby-de-la-Zouch in 1648. In 1650 he was imprisoned in the Tower of London and his lands were sequestrated. He continued his political activity, becoming a focus of royalist opposition in the Midlands, while Staunton Harold became a refuge for displaced Laudian clerics.
