thanks Rick, is there an index for Étienne's marriage perchance? That might possibly tell us who was present and any relation, might give a clue.
Renée Loppé's parents have the last names Loppé and mother is Després.
Marie Lemonnier (aka Mousnier)'s parents have the names Lemonnier / Mousnier.. and the mother is Esnault (can vary wildly)
Renée is actually from another location than Pierre; Marie is from La Flèche, as is Pierre.
