 A grammar school was established in 1603 by Alderman Valentine Broughton of Chester.The 1620 Norden's jury of survey of Wrexham Regis stated that four-fifths of the land-holding classes of Wrexham bore Welsh names and every field except one within the manor bore a Welsh or semi-Welsh name.During the English Civil War, Wrexham was on the side of the Royalists, as most Welsh gentry supported the King, but local landowner Sir Thomas Myddelton, owner of Chirk Castle, supported Parliament.
