Alexis (Alexandre) GAGNON & Anastasie BELANGER

I am looking for the family (Parent/siblings/children) of Alexis
(Alexandre) GAGNON & Anastasie BELANGER. I have a great deal on
Alexis's line back to Barnabe GAGNON in France, but nothing on
Anastasie BELANGER. I am looking for her siblings and Parents and
their families. Anything.

My Line comes down from Alexis through Francois Xavier and I am looking
to see where the other BELANGER line intersects upline from Anastasie.
I have a great deal of family line about Alexis and there are alot of
BELANGER in that line. Seems very interesting to me, any help filing
in the empty holes I have would be appreciated.
