It surprises me. I can find in some minoritary and unsourced pages about it but a nameless daughter for one of the main lords of France seems weird. Admittedly, one daughter could have died in infancy, but it wouldn't have let time to marry someone.
Critically in a period where the county of Geneva is disputed, between Amedée de Savoie that brought it from Odon de Villars and the heirs of this latter that didn't took, at my knowledge, the contal title.
I'm frankly a bit suspicious there : Have you some primary sources about it?
Anyhow, these marriages were made according a traditional angevine policy : alliance with France and securing Maine against Brittany.
I suppose a surviving third daughter could technically marry a Navarrese, but I would rather bet on Aragon or Savoy.
