Joseph  DUGRENIER dit PERRON

Québec Généalogie - What is a 'dit/dite' name?  When the first settlers came to Québec from France it was a custom to add a 'dit' nickname to the surname. The English translation of 'dit' is 'said'. The Colonists of Nouvelle France added 'dit' names as distinguishers. A settler might have wanted to differentiate their family from their siblings by taking a 'dit' name that described the locale to which they had relocated. The acquiring of a 'dit' name might also be the result of a casual adoption, whereby the person wanted to honor the family who had raised them. Another reason was also to distinguish themselves by taking as a 'dit' name the town or village in France from which they originated. This custom ended around 1900 when people began using only one name, either the 'dit' nickname or their original surname.

Joseph was a faux sauniers (salt smuggler) deported to Nouvelle-France after 1730.
Historically, a saunier, or salt manufacturer, harvested salt in salt marshes. In New France, however, a saunier was a salt merchant. Because of the high taxes levied on salt in France, especially the gabelle, salt merchants faced intense competition from faux-sauniers, traders dealing in contraband. These traffickers traded in salt without paying the tax.

Hundreds of convicted salt traffickers in France were deported to the colony of New France in the 18th century to work as labourers. It's a little known fact that these salt smugglers made a significant contribution to the settlement of Canada.
