French Ship and Nova Scotia Marriage

I had some information on one of my ancestors. The information was that
his name was Pierre Crépaux, born about 1657, and resident of l'isl
d'Elvire, Saint-Sebastien, la Tremblade, France. This Pierre had a son,

Alain Sappey...

Hello Dewey,

I am a bit confused about the french roots of Pierre...
I don't know any island named Elvire near La Tremblade.
May be the "Oleron" Island ???
I have checked with Geneanet and I have noticed a lot of CREPEAU going from
Oleron to Quebec in 17th century.

If it can help...

Regards from France,

Francois, who was recorded as the commanding captain of a ship named
Bonaventure in a record recording his marriage in Port Royale, Canada,
on 9 September 1705 to Marie Mius, daughter of Abraham Mius "sieur
d'Plemarche", France, and Marguerite de Saint-Etienne de la Tour, France.
Does anyone have anything on Pierre, the ship, or know where to get the
documentation on the marriage?
Merci,
Dewey Crepeau
