Sir William Saville of Thornhill Yorkshire, 3rd Baronet, ?1612 - 1643/4. He was a grandson of the sixth Earl of Shrewsbury. He matriculated from University College Oxford at the age of 14, succeeding to the Baronetcy 11 days later on the death of his brother. He was a student at Gray's Inn in 1628, Member of Parliament for Yorkshire from April to May 1640, and for Old Sarum from about February 1641 until disabled in September 1642. He was at one time Governor of York. In 1643 the Earl of Newcastle garrisoned Sheffield Castle for a seige, putting Sir William in charge. He in turn appointed Major Thomas Beaumont his deputy, placing him in full charge of the defence of the castle (and of Sir William's wife and children). Sir William then left for York, to assist the Earl of Newcastle. He took part in several battles, including Winceby, and died near York in 1643/4.
