Louis-Charles Le Sesne, Lord of Bourdin in his own right, married Eustache-Henriette de Buade in 1685. She was probably the daughter of Louis de Buade de Frontenac, who was a Protestant courtier and Governor General of New France (in Canada) from 1672 to 1682 and from 1689 to his death in 1698, so was in France at the time of the wedding. A first son was born in March the following year. He was baptised Charles-Henri Le Sesne de Menille de Themars on 15 March in the church of St Pierre in Loudun. Within weeks, his grandfather died and Louis-Charles swore allegiance for Ranton on 27 May 1686. Befitting his status, he took the title of Baron of Ranton.
