“ Benjamin Langlois, Esq., M.P., was a son of Pierre Langlois of Montpelier. There were several branches of the Langlois stock in France; his branch has been designated Langlois of Languedoc, and its armorial bearings have been certified thus:—

“ The grandfather of the refugee Pierre Langlois was Michael Langlois, who married, on 13th December 1620, Louise d’Arenes, and was the father of Captain Pierre Langlois of the regiment of Anjou, born in 1626; he died in France. The refugee, Pierre, was born in January 1673, and was a cornet of dragoons in England in 1692. He was naturalized by Act of Parliament in 1707. Afterwards he became a merchant, and married Mile. ”
