Jeanne d'Angoulême

Jeanne d'Angoulême, Countess of Bar-sur-Seine (ca. 1490 – after 1531/1538), Dame de Givry, Baroness of Pagny and of Mirebeau, was an illegitimate half-sister of King Francis I of France and princess Marguerite de Navarre. She was created suo jure Countess of Bar-sur-Seine in 1522. She was the wife of Jean de Longwy, Seigneur of Givry, Baron of Pagny and of Mirebeau.

Jeanne was born in Angoulême about 1490, the illegitimate daughter of Charles, Count of Angoulême and his mistress Antoinette de Polignac. Antoinette served as the chatelaine of the Charles' chateaux, and became a lady-in-waiting and confidante to his young wife Louise of Savoy whom he married on 16 February 1488.

When Charles died on 1 January 1496, Jeanne, her sisters, and her mother Antoinette were allowed to remain in the Angoulême household now presided over by Louise of Savoy, the widowed Countess. In 1499, Louise moved the family from the chateau of Cognac to the court of King Louis XII, who was her father's cousin. Jeanne was raised alongside her legitimate Angoulême siblings, Francis, who was now the Count of Angoulême, Duke of Valois and heir presumptive to the Kingdom of France, and Marguerite. She was legitimised in Lyon in August 1501 by Louis XII on the occasion of her marriage.

Jeanne had a full sister, Madeleine (died 26 October 1543), who became Abbess of Fontevrault and another half-sister, Souveraine (died 23 February 1551), from Charles' relationship with Jeanne le Conte. By her mother's marriage to Béraud of L'Espinasse, Seigneur de Combronde, Jeanne had another half-sister, Françoise of L'Espinasse. Jeanne's half-brother, Francis was crowned King of France on 25 January 1515. On 24 March 1522, she was created suo jure Countess Bar-sur-Seine by her half-brother Francis, who had succeeded Louis as King in 1515.
