"The Duke was but a stripling when he begat this fellow off a woman in the household. Her surname was Eauze. The bastard was raised under the name of Claude Eauze. He went off to India for a while to seek his fortune, and later made enough money in the slave trade that he was able—with a loan from his father—to buy a noble title in 1674 when they went on sale to finance the Dutch war. Thus he became the Marquis d’Ozoir, which I take to be a play on words, as his name, to that point, had been Eauze. Only a year before buying this title, he married none other than Charlotte Adélaide de Crépy: the younger sister of the duchesse d’Oyonnax."
