I usually rely upon Peter Gagne's book for data on Filles du Roi. He simply says "her origins in France are unknown" and he does not include any information on who her parents might be. I would remove any parents assigned to her.
Gagne, Peter J., "King's Daughters and Founding Mothers, The Filles du Roi, 1663-1673" (Woonsocket, RI, American-French Genealogical Society, 2001)
