This is an old post however I am looking for more on what was posted previous, "By the mid-1800's, Quebec's English government required that all dual-named Quebeckers drop one of their two names. Many elected to drop their original family surname and retain their "dit" name. The 1800's was also the time of considerable migration to the U.S. The U.S border officials required that a dual-named Quebec immigrant drop his first name."This is exactly what my ancestor did at that time and I would like to be able to source this information.Can you let me know where you found this.My ancestor Pierre Balard-dit-Latour dropped Balard-dit after his first marriage and in his second became only Pierre Latour.This is the first explanation I have heard and I would love to be able to source it.My original ancestor from the 1665 mission was Louis Balard d'Ausson dit Latour.Both d'Ausson and Latour were his dit names used while in service.I assumed because someone in Laubia company had already used Latour in the 1668 rolls of the men who stayed in Quebec.I hope to hear from you!
