There is no Vincent Plourde shown marrying a Delvina Landry in the St-Pascal Marriage Repertoire. However, there is a Fidele Plourde marrying a Delvina Landry on 12 January 1886 in St-Pascal, Kamouraska, PQ. Delvina is the daughter of Cyrille Landry and Ludivine Beaulieu.Furthermore, Fidele Plourde marries a Delima Landry, Delvina's sister, on 19 January 1891 in Mt-Carmel, Kamouraska, PQ. If you go to the following website and find Fidele Plourde, the son of Hyacinthe Plourde and Marie-Adele Dumais, the ancestry line to Rene Plourde will be a piece of cake.Linda Babin Jones does some of the best genealogical research that you will encounter. Since there is no Vincent Plourde shown in either St-Pascal or Mt-Carmel it is very likely that he was recorded as Fidele and not as Vincent.If Luc was born around 1900 then he would be the son of Delima rather than Delvina. Hope this helps you solve the enigma of Vincent & Delvina Plourde.My mother was a Plourde and I have a fairly comprehensive database of genealogical material pertaining to Plourdes, e.g., Jette, Tanguay, Drouin, PRDH, Riviere-Ouelle History, Talbot, Rimouski, Langlois, etc.
