This Day in History: 1410-03-16
On 16th March 1410, John Beaufort, 1st Earl of Somerset and first son of John of Gaunt, lord of Pontefract, and his mistress (at the time), Katherine Swynford, died. He had been born (sources quote 1371-73) whilst Gaunt was married to his second wife, Constance, and given the surname Beaufort after Gaunt’s French lands, Montmorency-Beaufort. Beaufort was created Earl of Somerset on 10th February 1397, only days after Parliament ‘legitimised’’ the four Beaufort children (John, Henry, Thomas and Joan) of John of Gaunt. Pope Boniface IX acceded to Parliament’s actions. Beaufort was the great grandfather of Henry VII.
