There were strong ties between Quebec and Louisiana in the 18th century. Louisiana was then part of New France, having been established by the French to block the British from expanding their influence westward in North America.
Many settlers who went to the southern part of the United States originated from the same regions in France as the French Canadians and the Acadians. But few Quebec historians or genealogists have focused on the links between the families of New France and those who settled in Louisiana.
An example of someone with personal links to both places was Pierre de Rigaud de Vaudreuil de Cavagnial, Marquis de Vaudreuil (1698-1778). His father was of noble descent, from the Languedoc region of France, and Pierre was born at Quebec, where his father served as governor-general of New France. Pierre served as governor of Louisiana from 1742 to 1753, and he was the last governor-general of New France, between 1755 and 1760.
Historian Mélanie Lamotte wrote an article about primary sources in North America and France for the early modern history of Louisiana when she was studying at the Cambridge University in the U.K. She currently teaches at Stanford University, and her Stanford website describes this article, “A Guide to Early Modern French Louisiana Sources” as providing “much-needed guidance on identifying and using French Louisiana sources. It lists the sources available and investigates their nature, details of access, state of preservation, as well as their state of digitization. It also suggests potential uses and interpretations that might be gleaned from such source material.”
