As the eldest, he was expected to succeed to be the head of the House of Pardaillan de Gondrin.
Known as the Marquis of Gondrin in his lifetime, he was outlived by his father and as such never succeeded to the Duchy of Antin which was created in 1711 by Louis XIV.
At the time of her first marriage, Marie Victoire, marquise de Gondrin, was a dame du palais to the king's granddaughter-in-law, the duchesse de Bourgogne, future Dauphine of France and mother of King Louis XV.
CORRECTION He died in 1758 in Arcadia (Nova Scotia) just before his family (second wife Marguerite dit La Sonde Marres and eight children) were all deported back to France (he likely died of a heart attack).
On 2 February 1723, Marie Victoire married again, in a secret ceremony, the Count of Toulouse, the legitimised younger son of Louis XIV and Madame de Montespan.
