Notes
About Jean Costé's parents: Nos Origines gives two answers.
What sources do we have about Abraham Costé?
What sources do we have about Marie Loiselle, the wife of Abraham?
None of these sources say that the couple had a son, Jean Costé.
None of these sources point to other authoritative sources.
Conclusion: For the time being, be aware that Abraham Costé and Marie (Françoise Geneviève) Loisel may or may not be Jean Costé's parents
