WikiTree and WikiData have differing dates in their corresponding death date fields for Jean Godefroy de Linctot (26 Mar 1678 and Jul 1681, respectively). This results in a "558 Wikidata - Different death date" suggestion. Sources found to date indicate a variety of possible death/burial dates for him, but I've been unable to find any contemporary sources for any of the potential death dates. It's likely that he died and was buried in or near Trois-Rivières, Nouvelle-France. A notarial act documents a donation that he made to 5 of his children on 22 Mar 1678, and his wife appears to be a widow in the census dated 14 Nov 1681, so he likely died between those dates. I was unable to find a burial record for him in the Family Search parish records for that location and time frame. Please see the Research Notes section of the profile for a discussion of all the potential death/burial dates and their sources.
The book Our French-Canadian Ancestors cites a source, Archange Godbout in Les pionniers de la région trifluvienne, première série: 1634-1647, La Bien Public, 1934, page 25. But I've been unable to find that source online or at my local library.
The sources are referenced inline in the Biography and Research Notes sections, and are all abstracted (mostly in English) at the end of the Research Notes section. For sources that are found online, links are included in the Sources section.
At this point, I've changed the status of the WikiTree death date field for Jean from certain to uncertain for the 26 Mar 1678 death date.
