Re: Jean-Baptiste Lacroix Dit Langevin
My findings are somewhat different than others posted.The original name is L'Angevin -- 'of' or 'to' the Angevins of Anjou.They held land grants in exchange of knight's service.There are references to the name in the medieval collection at Tours in relation to Eleanor of Acquitaine (1122-1204).Lacroix was 'de la croix' acquired during the crusades.
The first reference I find thus far to an individual is Maturin Langevin dit Lacroix who married Francoise Disle at La Lude in Anjou in 1600.His grandson and namesake - still a crusader and after a successful campaign against the Turks - came to Quebec to subdue the Iroquois in 1665 with the fabled 'Carignan Salieres' Regiment.
The reverse name first appears in 1786 at St. Jean, L'Acadie.It may have been a slightly dyslexic parish clerk.It's Lacroix dit Langevin in the left margin citation and is sometimes corrected to Langevin dit Lacroix in the text.Pierre Lacroix dit Langevin had four sons and J. Baptiste is probably a grandson.I've only followed Michel and the name order reverts in his line in his generation.You'll find all of them in the parish records of St. Marguerite de Blairfinde.In my line the Langevin is sadly dropped after 600+ years in the 1840's.
Hope this is helpful.
