Antigone of Gloucester, Countess of Tankerville
Antigone of Gloucester was an English noblewoman and the illegitimate daughter of Humphrey of Lancaster, 1st Duke of Gloucester( 1390 – 1447).

Humphrey, Duke of Gloucester
Humphrey of Lancaster, Duke of Gloucester (3 October 139023 February 1447) was an English prince, soldier, and literary patron.
He was (as he styled himself) "
son, brother and uncle of kings", being the fourth and youngest son of Henry IV of England, the brother of Henry V, and the uncle of Henry VI.
Gloucester fought in the Hundred Years' War and acted as Lord Protector of England during the minority of his nephew.
A controversial figure, he has been characterised as reckless, unprincipled, and fractious, but is also noted for his intellectual activity and for being the first significant English patron of humanism, in the context of the Renaissance.
Unlike his brothers, Humphrey was given no major military command by his father, instead receiving an intellectual upbringing.
Created Duke of Gloucester in 1414, he participated in Henry V's campaigns during the Hundred Years' War in France: he fought at Agincourt in 1415 and at the conquest of Normandy in 1417–9.
Following the king's death in 1422, Gloucester became one of the leading figures in the regency government of the infant Henry VI.
He proved a rash, impulsive, unscrupulous, and troublesome figure: he quarreled constantly with his brother, John, Duke of Bedford, and uncle, Cardinal Henry Beaufort, and went so far as to violently prosecute a dispute with the Duke of Burgundy, a key English ally in France, over conflicting claims to lands in the Low Countries.
At home, Gloucester never fully achieved his desired dominance, while his attempts to gain a foreign principality for himself were fruitless.
A staunch opponent of concessions in the French conflict, and a proponent of offensive warfare
, Gloucester increasingly lost favour among the political community, and King Henry VI himself after the end of his minority, following a series of setbacks on the war in France.
The trial in 1441 of Eleanor Cobham, his second wife, under charges of witchcraft, destroyed Gloucester's political influence.
In 1447, he himself was accused, probably falsely, of treason, and died a few days later while under arrest.
Humphrey was the exemplar of the romantic chivalric persona.
Mettled and courageous, he was a foil for the princess Jacqueline of Hainaut, his first wife.
His learned, widely read, scholarly approach to the early renaissance cultural expansion demonstrated the quintessential well-rounded princely character.
He was a paragon for Eton College and an exemplar for the University of Oxford, accomplished, diplomatic, with political cunning.
Unlike his brothers, he was not naturally brave, but opinionated, fervent and judgmental.
He exaggerated his own achievements, but idolized his brother Henry V. Despite the errors in both his public and private life, and the mischief he caused in politics, Gloucester is also at times praised as a patron of learning and a benefactor to the University of Oxford.
He was popular among the literary figures of his age for his scholarly activity, and with the common people for his advocacy of a spirited foreign policy.
For these causes he was known as the "good Duke Humphrey".
