Joseph Drouin, first established in 1917 a commercial-basis genealogical service that included its Dictionnaire national des Canadiens français (1608-1760), which was based on Tanquay's Dictionnaire, this work being carried by his son Gabriel in 1937. In the late 1950s, the Institut developed its own dictionary based on parish registers, which was indexed to allow quick, efficient research. Such genealogical innovations as developed by the Institut likely prompted the Franciscan priest Archange Godbout to found in 1943 the Société généalogique canadienne-française, the first such Québec genealogical society based in Montreal. Today the Fédération québécoise des sociétés de généalogie now includes 70 member genealogical societies, none of whom however have a national-scope genealogical dictionary. In terms of worthy successor to Tanguay's Dictionnaire, French-Canadian genealogy had to wait until 1983 for René Jetté to come up with his Dictionnaire généalogique des familles du Québec des origines à 1730, which is based on Montréal University PRDH's (Programme de recherche en démographie historique) Répertoire des actes de baptême, mariage, sépulture et des recensements du Québec ancien. In 2002, Jetté's PRDH colleague Bertrand Desjardins made available the Gaëtan Morin Éditeur CD-ROM Dictionnaire généalogique du Québec ancien des origines à 1765. In 2013, the Institut généalogique Drouin (bought out by Jean-Pierre Pepin in 1997 or 1999) entered into a partnership with Montréal University's PRDH and BALSAC project's UQAC, Laval et McGill universities to ensure full indexing and diffusion of Institut's LAFRANCE database of Québec civil vital statistic records in the XIXth century. In his examination of L'Ancêtre articles published over the last 18 years since publication of his 2019 article referenced here, Fortier found that Tanguay's Dictionnaire was cited in 10% of articles, that is, far behind Jetté's 41% and PRDH's 49%. Thus it is only in recent years that Cyprien Tanguay's Dictionnaire was substantially rehabilitated. References Bibliography Allaire, Abbé J.-B.-A.
