Giovanna di Coesme

Jeanne de Coësme, Dame de Lucé and de Bonnétable (1555 – 26 December 1601) was a French noblewoman and courtier. She was the daughter of Louis de Coesme and a member of the House of Bourbon. She married François de Bourbon, titled the Prince of Conti. As such, after her marriage she was the Princess of Conti.

Early life Jeanne was born in 1555. She was the daughter of Louis de Coesme (1532–1563), Seigneur of Lucé, and Anne de Pisseleu (the niece of Anne de Pisseleu, Duchess of Étampes, the mistress of King Francis I).

Her paternal grandparents were Charles III de Coësmes, Baron of Lucé, and Gabrielle d'Harcourt (a daughter of François d'Harcourt, seigneur de Bonnétable and Anne de Saint-Germain). Through her father, Jeanne was the heiress of Bonnétable, a commune in the Sarthe department in the region of Pays de la Loire in north-western France, which included the Château de Bonnétable (built by her paternal grandmother's grandfather, Jean d'Harcourt, in 1476).

Personal life Her first marriage, in January 1576, was to Louis de Montafié (1550–1577), Count of Montafié, Lord of Piedmont, Prince of Carignano. He was the son of Georges de Montafié and Bianca Orsini. Together they had one son and two daughters, The letters written by Jeanne during the 1580s and 1590s provide historians with an insight into the state of affairs in the province of Maine at that period.

Jeanne contracted smallpox while travelling to her estate at Lucé to negotiate Anne's marriage, and died at Saint-Arnoul, near Chartres, the day before Anne's wedding. In this marriage, Anne brought her inheritance of the countship of Montafié in Piedmont as well as her mother's seigneuries of Bonnétable and Lucé to the Bourbons.

Descendants Through her daughter Anne, she was posthumously a grandmother of: Louis de Bourbon, Count of Soissons (who had one illegitimate son, Louis Henri, Count of Noyers, by his mistress Élisabeth des Hayes); Louise de Bourbon, Mademoiselle de Soissons (wife of Henri d'Orléans, Duke of Longueville); Marie de Bourbon, Countess of Soissons (wife of Thomas Francis, Prince of Carignano); and Charlotte Anne de Bourbon and Élisabeth de Bourbon, who both died young.
