Description: Henry Pierrepont, 1st and last Marquess of Dorchester was born in March 1606/7. He married Hon. Cicelia Bayning, daughter of Sir Paul Bayning, 1st Viscount Bayning of Sudbury and Anne Glemham, before 1630. He was member of parliament for Nottinghamshire, and was called to the House of Lords as Baron Pierrepont in 1641. During the earlier part of the Civil War he was at Oxford in attendance upon the king, whom he represented at the negotiations at Uxbridge. In 1645 he was made a privy councillor and created Marquess of Dorchester; but in 1647 he compounded for his estates by paying a large fine to the parliamentarians. Afterwards the Marquess, who was always fond of books, spent his time mainly in London engaged in the study of medicine and law, his devotion to the former science bringing upon him a certain amount of ridicule and abuse. After the Restoration he was restored to the privy council, and was made recorder of Nottingham and a fellow of the Royal Society. Dorchester had two daughters, but no sons, and when he died in London on the 8th of December 1680 (aged 73) the title of Marquess of Dorchester became extinct. He was succeeded as 3rd earl of Kingston by Robert (d. 1682), a son of Robert Pierrepont of Thoresby, Nottinghamshire, and as 4th earl by Robert's brother William (d. 1690).
