Arthur de La Fontaine - Source Request

It’s showing up in unsourced web trees.

I do see https://en.m.wikisource.org/wiki/Memoirs_of_a_Huguenot_Family/Chapt... referenced, but it doesn’t actually go back that far.

I find the wife’s name, de Gordon, also highly suspect.

I'm not sure if this is a very good possible hint, but Friar Jean de La Fontaine of the Franciscan community in Amboise was the Confessor selected by Joan, sister of Charles VIII of France. I'm trying find a biography on Friar Jean de La Fontaine, but I'm so far at a loss as to where I can look. If we can find some information on him - parents and children - then we can "probably" connect our family with all the other claims that to date are not with sources/references. We do know from the Memoirs of my direct ancestor James Fontaine (peace be upon him) that "John de la Fontaine was born in the province of Maine, near the borders of Normandy, about the year 1500; and as soon as he was old enough to bear arms, his father procured him a commission in the household of Francis I., in what was then called "Les Ordonnances du Roi." It was in the tenth or twelfth year of that monarch's reign that he entered his service, and he conducted himself with such uniform, honor and uprightness, that he retained his command, not only to the end of the reign of Francis I., but during the reigns of Henry II., Francis II., and until the second year of Charles IX., when he voluntarily resigned. " (Your reference: https://en.m.wikisource.org/wiki/Memoirs_of_a_Huguenot_Family/Chapt...) Any ideas?

The problem with that reference is that though its author says the line goes back into nobility, he does not want to write about the line, because that's not what his children should be thinking about.

So it's got hints, but it's a dead end in terms of actual evidence and clarity of line.
