My great-grandmother was also the same Aurélie Duteau. She was actually a Bluteau as her grandfather was born Jean-Baptiste Bluteau and married Agathe Birtz dite Desmarteaux. I would like to share information with you. I have Aurélie's birthdate as 15 June 1850 in Lacolle. Mary's name was actually Flavie, and you will find this name in some of the church records in Northampton as well as the baptism records in Lacolle.
