Mathurin Guyon has a profile in WikiTree which makes him the father of Jacques Guyon (documented father of the pioneer Jean Guyon du Buisson) and the son of Jean Guyon des Granches, conveniently making the pioneer Jean Guyon the great-great nephew (by marriage) of explorer Jacques Cartier.
Unfortunately, there are a few problems:
Looking closely at Jacques Guyon's profile, his parents should probably be unknown. No reputable source names them.
Going up one generation, the only sources for Mathurin are:
- Généalogie Québec, relying on emails from a mysterious (and ubiquitous) contributor.
- Geni - I could go back to their source, which is: "Denis Beauregard, Dictionaire généalogique de nos origines, Tome 1 1608-1730, Ière Edition, Productions FrancoGène, 1998, p. 50."
- A Find a grave memorial (no picture, no grave, no date or place of death - and I would not expect any in this time and place unless the person was a notable buried IN the church - and it would need a big notable to have a surviving inscription) which is a new version that apparently contradicts an earlier one
- Rootsweb/Worldconnect (unsourced)
- Ancestry links (on the profile; I can't access).
Mathurin also has a similarly unsourced wife, two unsourced children (in addition to Jacques), an unsourced mother, and 6 unsourced siblings. Thanks to a couple of secondary sources, we know that the profile set as his father existed and that he was Jacques Cartier's brother-in-law, but we have no credible source confirming him as Mathurin's father.
The only lead I have is that Geni cites Denis Beauregard, but if you look at Jacques Guyon's profile on Beauregard's site, you see that his parents are not mentioned. No Mathurin.
To sum up:
- Should Jacques Guyon be left with unknown parents?
- Did Mathurin Guyon exist?
