Eleanor, Duchess of Gloucester

Eleanor Cobham (c.1400 – 7 July 1452) was an English noblewoman, first the mistress and then the second wife of Humphrey, Duke of Gloucester. In 1441, she was forcibly divorced and sentenced to life imprisonment for treasonable necromancy, a punishment likely to have been politically motivated.

Early life Eleanor was the younger daughter of Sir Reynold Cobham (d. 1445), who lived at Sterborough in Surrey, and his first wife, Eleanor Culpeper (d. 1422), daughter of Sir Thomas Culpeper.

Mistress and wife to the Duke of Gloucester

In about 1422 Eleanor became a lady-in-waiting to Jacqueline d'Hainault, who had fled to England in 1421 and divorced her husband, John IV, Duke of Brabant. In 1423, Jacqueline married Humphrey, Duke of Gloucester, the youngest son of King Henry IV, who since the death of his elder brother King Henry V was Lord Protector of the child king Henry VI and a leading member of his council. Jacqueline's divorce was only valid in England, and the marriage to Gloucester was arranged in haste and secret, but in 1424 Gloucester went to France to wrest control of his wife's estates in Hainault. In January 1428, the Duke's marriage to Jacqueline was annulled, as Pope Martin V decreed that Jacqueline was still the wife of John IV, Duke of Brabant when she had remarried. Gloucester was then free to wed, and married Eleanor. Over the next few years the couple were the centre of a small but flamboyant court based at their principal residence La Plesaunce in Greenwich, surrounded by poets, musicians, scholars, physicians, friends and acolytes.

In 1435, Gloucester's elder brother, John, Duke of Bedford died, making Humphrey heir presumptive to the English throne. The astrologers were Thomas Southwell (physician and canon of St Stephen's Chapel in the palace of Westminster) and Roger Bolingbroke (an Oxford scholar and member of Duke Humphrey's household). They predicted that Henry VI would suffer a life-threatening illness in July or August 1441. When rumours of the prediction reached the king's guardians, they consulted other astrologers, who could find no such future illness in their astrological predictions. This was a comfort for the king, who had been troubled by the rumours. They also followed the rumours to their source and interrogated Southwell, Bolingbroke, and John Home (Eleanor's personal confessor and canon of Hereford and St Asaph).

Eleanor, subject only to the ecclesiastical jurisdiction whilst in sanctuary, was examined by a panel of bishops headed by Henry Chichele, Archbishop of Canterbury. and ‘forto have borne a child by hir lord, the duke of Gloucestre’.

Eleanor and her fellow conspirators were found guilty. Southwell died in the Tower of London, Bolingbroke was hanged, drawn and quartered, and Jourdemayne was burnt at the stake as a relapsed heretic. Eleanor had to do public penance in London, was divorced from her husband, and was condemned to life imprisonment with appropriate accommodation in the royal castles and a royal pension of 100 marks a year.

On each of three market days in November 1441 she was forced to walk barefoot to a different church carrying a taper. Market days were chosen as they were busy, to maximize the humiliation. The bishops found that Eleanor had also used witchcraft to "enforce" Gloucester "to loue her and to wedde her". This stripped her of her titles and rights to any of the duke's wealth. In 1442, Eleanor was imprisoned at Chester Castle, then in 1443 moved to Kenilworth Castle. This move may have been prompted by fears that Eleanor was gaining sympathy amongst the Commons, for just a few months prior an unnamed Kentish woman had met with Henry VI at Blackheath and scolded him for his treatment of Eleanor, saying he should bring her home to her husband. Kenneth Hotham Vickers, Alison Weir and Cathy Hartley all suggest that Eleanor was their mother, though other authors treat their maternity as unknown. Antigone, however, had her first child in November 1436 suggesting she was born at the very latest in 1424, which may suggest that she was born before Eleanor became involved with Humphrey. Thus, Eleanor's children may have been: Arthur Plantagenet (died after 1447) Antigone Plantagenet, who married Henry Grey, 2nd Earl of Tankerville, Lord of Powys (c. 1419–1450) and then John d'Amancier.
