I'm looking for the parents of Elizabeth Deguire Therrien (1833-?), married  to Ambroise Therrien (1833-1917). they have a daughter named Alvina (Elvina) Montpellier (Therrien born 1864-1947) married to Pierre Oscar Montpellier (1864-1947).  On this site Ambroise is not married and the Elizabeth Deguire is not the correct one that I'm looking for!! Thank you for your time!

this is going to be long and complicated reply

in the marriage index book for St Michel Vaudreuil,   Quebec

  the  marriage    is 18-8-1857

 Amboise Therrien ( Jos.& Marguerite Pilon)

under the entry it states she was also named Sophie or Elisabeth at the birth of her children

beleive me   this is    an  unusual notation

 but here she is  .......Marie Louise ( Francois-Wencilas and Sophie Deguire

the family of Ambroise is reconstructed on rootsweb world connect

it  seems to be the right one  all children inOntario

it is   Elisabeth with an S

the link for rootsweb world connect 

for the children etc....

DEGUIRE 

the index card for Wenceslas Deguire is on this site

it should resolve your  question

he is not  under  Francois

hope it helps

Sorry this does not give me what's I am looking for. I'm trying to find Elisabeth's mom and dad.  This seems to be a mystery!!

her parents are listed  in brackets next to her name 

in my response 

Francois Wenceslas Deguire and Sophie Deguire

I stated  that  she was married under Marie Louise

according to the church register 

I don't understand  your reply

Sorry I didn't quite understand that was what you were stating that  they were her parents! Thank you so much for your help. I'm on the right track now!!

the good date is 18 of August 1856 St-Michel de Vaudreuil
