Pierre Lafleur and his wife Jeanne Palud lived in the Breton fishing village of Roscanvel, near Brest; it is on a rocky peninsula facing the Atlantic (the photo above is its parish church). Their son Pierre was born there in January 1702; his mother died two years later. There were two sisters, Marguérite (1696-1700) and Marie (1698-1704). Pierre became a marine in the compagnie de Duvivier, which was sent to Canada about 1730; there he met and married Angélique Lecompte in November 1731, at Montréal. Their descendants are the only Lafleur family in Québec.

Our ancestor Josephte Lafleur married Joseph Bourré in about 1775, and their daughter Marie-Louise Bourré married Louis Boucher in November 1796 at St-Charles-sur-Richelieu. Beyond that we know nothing about Josephte. She could be a descendant of the Pierre Lafleur mentioned above, but there are also at least a dozen families who used Lafleur as a "dit" name; she may have come from one those. Or she may have been an immigrant, but that is unlikely in the late eighteenth century.
