Thomas de Furnival, 1st Baron Furnival, who had a summons, in the 22nd of Edward I, amongst other great men, to attend the King in order to advise of the affairs of the realm, and having done so, received command to repair to Portsmouth, upon the first of the ensuing September, well fitted with horse and arms, for the expedition then intended against France. In the next year, 23 June, 1295, he was first summoned to Parliament as a baron, and from that period his lordship appears, for several years, to have taken a distinguished part in the Scottish wars. In 27th of Edward I he was constituted Captain-General and Lieutenant to the King, for the Counties of Nottingham and Derby, and had summons to Parliament uninterruptedly until 27 January, 1332, 3rd of Edward III, but he did not hold lands by barony. Lord Furnival married Elizabeth, daughter of Peter de Montfort, Jr., of Beldesert Castle, County Warwick, and was succeeded at his decease by his eldest son, Thomas.
