Ramezay was survived by two sons and at least five daughters. In 1711 his eldest son, 19-year-old Claude junior, an ensign in the French navy, lost his life in an attack on Rio de Janeiro. His second son, Louis, Sieur de Monnoir, was killed by the Cherokees during the campaign of 1715 against the Fox Indians. In 1712 Ramezay's third son, Charles-Hector, Sieur de La Gesse, was presented to the French court by Madame de Vaudreuil. La Gesse, the elder of the surviving sons, died on 27 Aug. 1725 in the wreck of the "Chameau" off Île Royale. The younger, Jean-Baptiste-Nicolas-Roch, entered the military and is perhaps best remembered as the man who surrendered Quebec to the British in September 1759. Of the five daughters, two became nuns and two others married officers of the colonial regular troops.
