Gerard de Lisle, 1st Baron Lisle (1304 – 9 June 1360) was an English nobleman and soldier during King Edward III's campaigns in Scotland and France.
He was born about 1304 (aged 23 in Feb. 1327, aged 40 in 1350). He resided chiefly at Stowe Nine Churches in Northamptonshire and Kingston Lisle (in Sparsholt), Berkshire (now Oxfordshire). He was the son and heir of Sir Warin de Lisle, of Kingston Lisle (in Sparsholt), Berkshire, Keeper of Windsor Castle, by Alice, daughter of Henry le Tyeys, 1st Lord Tyeys. He was knighted in 1327. In 1329 he proved his right to free warren in his demesne lands at Stowe and Kislingbury, Northamptonshire by grant of King Henry III to Geoffrey de Armenters. In 1332 Richard Herman was attached to answer Gerard de Lisle concerning a plea why with force and arms he broke the close of the said Gerard at Alverston, Hampshire and dug in his separate soil there, and took and carried away twenty cartloads of earth extracted therefrom to the value of 40 shillings, and depastured, trampled on, and consumed his grass once growing there to the value of 60 shillings. In 1339 Gerard had a dispute with his mother, Alice, regarding the presentation of the church of Stowe, Northamptonshire, but admitted it was not his turn to present; he also complained of trespass on his park at Stowe.
He served on the English side in the Second War of Scottish Independence in 1333 and 1335, under Richard FitzAlan, 10th Earl of Arundel. He served with him again during the Hundred Years War in France and fought at the Battle of Crecy.
He married (1st) after 3 Dec. 1329 Eleanor de Arundel, widow of William de Saint John, and daughter of Edmund de Arundel (or Fitz Alan), Knt., 9th Earl of Arundel, by Alice, daughter of William de Warenne, Knt. They had one son, Warin, Knt. [2nd Lord Lisle]. In 1338 he made a settlement of the manors of Stowe and Church Brampton, Northamptonshire on himself and his wife, Eleanor. His wife, Eleanor, was living c.1342, in which year Gerard sued his receiver, John son of Robert de Hulle, regarding various monies received from various manors, among them Abbotstone, Hampshire and Walberton, Sussex, which Eleanor held in dower of her first marriage. In 1347 he was contracted to marry Margery, widow of Nicholas de la Beche, late Constable of the Tower of London, but she was abducted by Sir John Dalton and married him instead. He presented to the churches of Abbotstone, Hampshire, 1349, and Mundford, Norfolk, 1349 and 1352.
He married (2nd) before 1 July 1351 (date of settlement) and possibly as early as 29 July 1349 (date of his presentation to Abbotstone church) Elizabeth le Strange, widow of Edmund de Saint John (died at Calais 18 Aug. 1347), 3rd Lord Saint John of Basing, and daughter of John le Strange, Knt., 2nd Lord Strange of Blackmere, by Ankaret, daughter of William le Boteler, 1st Lord Boteler of Wem. They had two sons, Richard and Henry, and one daughter, Elizabeth (wife of Edmund de Stonor, Knt., of Stonor (in Pyrton), Oxfordshire).
In 1351 Philip Warde, formerly bailiff of Gerard de Lisle in the manor of Walberton, Sussex, owed him a debt of £10 7s. He was summoned to Parliament from 15 Dec. 1357, by writs directed Gerardo de Insula or del Idle, whereby he is held to have become Lord Lisle. He was summoned to a Council 20 June 1358.
His widow, Elizabeth, married (3rd) Richard de Pembridge (or Pembrugge), K.G., of Orwell, Cambridgeshire, Burgate and Lyndhurst, Hampshire, etc., Warden of the New Forest, Governor of Bamborough Castle, Governor of Dover Castle and Warden of the Cinque Ports, Chamberlain of the Household. She died 14–16 Sept. 1362.
