Lady Barbara FitzRoy

Barbara and her mother, by Thomas Pooley

Barbara was born at Cleveland House in St Martin in the Fields, London, England on 16 July 1672.[2] Around the time she was born, Louise de Kérouaille was replacing her mother as the king's primary mistress.

Although her mother insisted she was a daughter of the king, Barbara was probably fathered either by John Churchill, later Duke of Marlborough, a second cousin of her mother, or Lord Chesterfield, whom she is said to have resembled in her features.[3][4] Boyer in his "Annals", published in the lifetime of the Duke of Marlborough says of Barbara:

"I do not find the King ever owned her for his daughter; but a great man now living is her reputed father. [...] It is generally believ'd that Mr. Churchill, afterwards Duke of Marlborough, was her father."[5]

Finally, it may be remarked that her mother's husband, Lord Castlemaine, believed her to be his daughter, and bequeathed her his estate.[6] Charles, however, always insisted on acknowledging her as his child, while disavowing her in private.[3]

She and her mother were painted by Thomas Pooley in 1677. They are seen holding a basket of flowers; Barbara Fitzroy is portrayed as a smiling, round-faced five-year-old with blonde curls.[7]

The king died in 1685. In March 1691, eighteen-year-old Barbara gave birth to the illegitimate son of the Earl of Arran,[8] whom she named Charles Hamilton (1691–1754). Charles went on to marry first Elizabeth, daughter of the Hon. John Campbell of Mamore and had a son christened William James (the surname was taken after his grandfather), but he died in infancy. The main reason for the name change was to distance him from the Hamilton family who had sent Charles out to France after the disgrace of his father's affair and bastard child. While in France Charles Hamilton was styled Count of Arran. Elizabeth later died and Charles remarried Antoinette Courtney, daughter of Charles Courtney of Archambaud and had two sons by her. Their elder son, Charles Hamilton died without issue, and a younger son, William James (christened with the surname James as with his namesake older brother) who returned to England and began a military career, finally settling in Dorset. William on returning to England went into the Army, became a Lieutenant Colonel in the Royal Scots Greys and was created a Knight Companion of the Order of the Bath. He went on to marry Catherine, daughter of Sir Gerrard Napier, 5th Baronet of Middle March and had a son, who married the daughter of John Montagu, 5th Earl of Sandwich.[8][9] Arran's parents bitterly opposed his relationship with Barbara. After giving birth, she became a nun[8] in the English Priory of St. Nicholas, at Pontoise in Normandy, France, taking the name Sister Benedicta, where she later became prioress in 1721. Her son was raised by her mother, the Duchess of Cleveland, who supposedly disowned her.[8]

An autograph of the Prioress is as follows:

Mon nom du monde est Barbe Fitz Roy est en Religion Benedite fille Du Roy De La grande Bretagne Charles 2dc j'ay fait profession dans Le Couuent des Benedictines Angloiscs De Pontoise L'annee 1691 Le 2* D'auril c'est maison est mittige.[5]

Roughly translated as:

My name in the world is Barbe Fitz Roy, in Religion it is Benedicta, daughter of the King of Great Britain, Charles II. I made profession at the Convent of the English Benedictines in Pontoise, the year 1691, the 2nd of April. It is my place of penance.

The Lady Barbara died there in monastery on 6 May 1737, and lies buried in the church of the Priory.
