AILLEBOUST DES MUCEAUX (Musseaux), JEAN-BAPTISTE D’, half-pay lieutenant, business man; b. 27 March 1666 at Montreal, son of Charles-Joseph d’Ailleboust* Des Muceaux and Catherine Legardeur de Repentigny; d. and buried 2 Sept 1730 at Montreal.

He first chose a military career, and was promoted in 1690 to the rank of half-pay lieutenant. The following year he quit the service, left Quebec to go to Montreal, and devoted his energies to the wine trade, which led him to travel in the pays d’en haut.

Jean-Baptiste d’Ailleboust is chiefly known through a curious ruling handed down with respect to him by Bishop Saint-Vallier [La Croix] on 26 May 1719, which by refusing absolution censured his relations with his servant, the daughter of Paul Haguenier. The penalty was imposed not only on the guilty couple but also on d’Ailleboust’s wife and the concubine’s father, who were expected to use their influence to bring to their senses the husband and the daughter respectively.

On 19 April 1689, at Quebec, Jean-Baptiste d’Ailleboust had married Anne Le Picard, Vital Oriol’s widow, who was buried on 20 July 1736 at Montreal. He had 16 children.
