Louise Marie Madeleine Fontaine
Louise-Marie-Madeleine Guillaume de Fontaine (after marriage known as Madame Dupin; 28 October 1706 – 20 November 1799) was a French "saloniste".
Guillaume Desautels
He was married in 1548 to Jeanne de Bruyere. Other researchers give the name of Jane de Salle. It is not known if there were any children from this marriage or if, in fact, there were two distinct marriages. 
His maternal grandmother, also named Anne, was the sister of Etienne de Tyard, father of Pontus de Tyard, one of the seven members of the group of French poets called the Pléiade. Guillaume's mother, Anne de la Vesure would thus have been the first cousin of Etienne.
