(c.1318 – 7 March 1369),[1] of Bures St. Mary, Suffolk, was an English nobleman and soldier.
[2] On account of the valiant conduct of his father, Thomas, who died in 1339 in battle at the storming of Hunycourt in Vermandois, France, the King received Michael's homage, though the latter was under age, and granted him livery of his lands and the full benefit of his marriage, taking security for the payment of the relief.
Rayment stated that Thomas de Poynings was summoned to Parliament on 23 April 1337,[3] which would indicate that he was the first baron, but Cokayne held a contrary position, which is that Thomas was summoned to 'a council of prelates and magnates'.
William married Michael's daughter Agnes, who by the name of "Agnes Bardolf" is mentioned as a legatee in the will of her mother, Joane Lady Poynings, dated 12 May 1369, and by that of "Lady Bardolf my sister" in the will of Thomas Lord Poynings, dated 28 October 1374.
Poynings married, before 1348, Joan Ruxley (d. 11 May 1369), widow of John de Moleyns, son and heir apparent of John, Baron Moleyns,[2][1] and daughter of Sir Richard Rokesley.
