Sir Henry Slingsby of Scriven, 1st Baronet, 14 January 1602 – 8 June 1658, was an English landowner, politician and soldier who sat in the House of Commons at various times between 1625 and 1642. He supported the Royalist cause during the Wars of the Three Kingdoms, and was executed in 1658 for his part in a conspiracy to restore Charles II. His ‘Memoirs’, covering the years 1638 to 1648, were first published in 1806 and are a valuable first-hand source for the civil war period in northern England. Source: Wikipedia (en)
