Lambert d'Yvois (Lambert d'Epargnemaille)

Lambert d'Epargnemaille, called d'Yvois, was the thirtieth regular abbot of Notre-Dame de Mouzon. When his predecessor Pierre I de Fismes resigned to Guillaume de Trie, archbishop of Reims, in April 1332, the abbey on the Meuse stayed vacant until 6 January 1333, when Trie, by compromise, appointed Lambert, a kinsman of the châtelains of Yvois. Accused of simony over his promotion, he cleared himself and was solemnly blessed by Trie.

His seal of 1334, a silver sun-shaped vessel and a chalice he gave the house all bore the arms of the châtelains of Yvois. A charter of 1339 still names him living, and he had died by 1345.
