illegitimate half-sister of the admiral, mistress of Louis XV; married, she had numerous descendants, including two daughters by Louis XV. 4° L'Abbé Charles d'Estaing (ca1595-1661), lord of Cheylade, Knight of the Order of Saint John of Jerusalem. He died in 1661 with a debauched reputation, having made two wills in which he recognised a natural daughter but no son. However, the Giscard d'Estaing genealogy attributes their paternity to Joachim d'Estaing, lord of Réquistat. No birth record or other document exists for Charles' daughter. Other Destaing or d'Estaing families Destaing of Cantal Notable legal family, established in the Carladès, with noble connections from the start of the 16th century, ending with : Zacharie Destaing (Aurillac 1764 - Paris 1802), general, son of Pierre Destaing and Marie-Gabrielle Delzons, seventh generation descendant of : Jehan Destaing, lord of Labouygues, royal notary in Marcolès, in the Cantal département, and Souveraine de Chivialle. It could be a collateral branch of the d'Estaing family. Destaing of Réquistat Following a request, the Giscard family was authorised in 1922 to add to its name "d'Estaing", even if no link between the two families was ever proved : Edmond Giscard (1894–1982) is a descendant: ninth generation of Joseph D'Estaing (Jabrun 1648 - Jabrun 1711]), son of Joachim D'Estaing and Suzanne Paulet, self-styled noble, lord of Réquistat and of Boissière, with remote kinship with Jean d'Estaing who bought the Château de Réquistat around 1669 to give to his daughter Marie-Claire. This Joachim I d'Estaing, sieur de Réquistat (1610–1685), was illegitimate son of Charles d'Estaing (1585–1661), sieur de Cheylade, Knight of Saint John of Jerusalem, son of Jean III d'Estaing, seigneur de Val (1540–1621) and his wife, Gilberte de La Rochefoucauld (1560–1623). As an illegitimate son, was condemned as a usurper of nobility by a judgement of 5 May 1667. His descendant, Lucie Madeleine d'Estaing, Dame de Réquistat (1769–1844) is the female ancestor from whom the Giscard d'Estaings took their name.
