Clothilde-Marie-Catherine, called Catherine, was the elder daughter of Paul Sigisbert Moitessier, a lawyer and businessman, and his wife, Marie-Clotilde-Inès, née de Foucauld. On 23 January 1862, in the church of Madeleine le jeudi, she married Raymond-Gaspard-Auguste-Emmanuel, Comte de Flavigny [1838-1887]; they had no children. The Comte de Flavigny was an attaché of the French Ambassador, and for this reason the couple lived for a time in Italy. Catherine died on 14 June 1914 in Paris, and is buried at Monnaie, Indre-et-Loire; her husband predeceased her in 1887. Catherine's mother was the subject of two portraits by Ingres, which came into Catherine's possession after her mother's death. After Catherine's death, the portraits passed or were bequeathed to her younger sister Françoise-Camille-Marie, called Marie, who in 1874 had married Olivier-Archille-Gabrielle, Vicomte Taillepied de Bondy.
