Pierrepont, Henry, 1st Marquess of Dorchester (1606 -1680)
Henry Pierrepont was the eldest son of Robert Pierrepont, 1st Earl of Kingston, and Gertrude, daughter and coheir of Henry Talbot, fourth son of George Earl of Shrewsbury. In the Parliament of 1628 1629, as Viscount Newark, he represented the County of Nottingham, and on 11 January 1641 he was summoned to the House of Lords as Baron Pierrepont, of Holme Pierrepont. He took an active part in raising forces for the Royalist cause during the Civil War. Succeeding his father in 1643, he followed the King to Oxford, and remained in attendance to the end, being rewarded with the Marquessate of Dorchester on the 25 March 1645. He was one of the King's commissioners at the Treaty of Uxbridge, but compounded for his estates in March 1647. He then settled to study, particularly medicine and law. He was a Fellow of the College of Physicians, was very proud of his knowledge of medicine, and left his library, valued at £4.000, to the College.
