In Robert J. Quintin's book Genealogical Dictionary of French Canada published Jun 1993 Vol A, p 1113, he lists Pierre Aubry & Elisabeth Antoine as being of Sire, Tours, Lorraine with 2 sons:
Nicolas 1 m Marie-Anne Juneau 08-01-1759
Grenadier of Languedoc Regiment, made prisoner of English in 1759
I suspect the marriage you are looking for took place in France, as he does not give the date. Have you tried Fiche-Origine to see if Beauregard has it listed?
