I found the following notation in https://www.fichierorigine.com/recherche?numero=240043
Quatre soeurs et un frère sont baptisés à La Flèche (St-Thomas) : Françoise, le 29-04-1634 ; Étiennette (homonyme), le 17-10-1635, inhumée le 04-12-1635 ; Charlotte, le 22-11-1636, inhumée le 05-01-1638 ; François, le 29-11-1641 et Marie, le 22-12-1642.
Can anyone explain where the 'dite Antoniette Alton' comes from? I see her mother's name was Antoinette. Does this mean she was 'called' Antoinette? All the original source documents list her as Etiennette which a not uncommon name. The Alton surname is also listed as Hatton in some of these. Wondering which is correct! Has anyone found more definitive information?
