Genealogist, Lucie LeBlanc Consentino, says: Radegonde Lambert married Jean Blanchard (not Jean-Baptiste) and their parents are unknown.
BLANCHARD, Jean, came from France with his wife, according to Jean LeBlanc, husband of his great-granddaughter Françoise Blanchard (Doc. inéd., Vol. III, p. 43). The deposition of Françoise's nephews Joseph and Simon-Pierre Trahan is to the same effect (ibid., p. 123). Both depositions mistakenly give Guillaume as the ancestor's given name. Jean LeBlanc makes an additional error regarding the name of Jean Blanchard's wife, calling her Huguette Poirier. The censuses of 1671 and 1686 meanwhile clearly show that she was named Radegonde Lambert (see DGFA-1, pp. 143-144). The source of these errors is probably a simple confusion arising from the fact that Jean LeBlanc?s wife's grandfather Martin Blanchard had a brother Guillaume who was married to a woman named Huguette, as this writer explained in an article published in 1984 (SHA, Vol. XV, pp. 116-117). This Huguette was not named Poirier, however, but Gougeon, although her mother, Jeanne Chebrat, had married a man named Jean Poirier before she wed Huguette's father Antoine Gougeon, and all her male-line descendants in Acadia were Poiriers. Unfortunately, we do not know just what questions Jean LeBlanc asked in trying to establish the Blanchard lineage, but he might certainly have had the impression that Huguette was a Poirier from the fact that so many of her relatives were Poiriers, including her grandnephew Joseph, who was also on Belle-Île in 1767 (see Doc. inéd., Vol. III, pp. 13-15).
