Charlotte is said to be from Bayeux. The alleged parents from Allier. The first thing I would do is take a look at a map of France and see if this looks likely. People tended to marry in their village or the next. Though there are exceptions - the nobility, specific trades sometimes, and then people who moved to specific places where there would find people from their religious community (think La Rochelle, or Montbéliard).
So, a pairing of Charlotte from Bayeux with this parents can not be envisaged without knowing their story and having a justification for their moving from Bourbonnais to Normandy. It was not a small move. Or in other words - what you have here is implausible, on top of being unsourced. (note: more improbable things have happened, of course. I don't want to sound judgmental. Just trying to evaluate what is likely).
