Dussault or Dufaut or Dufault

I am looking for any information on a Pierre Dussault or Dufaut that was born-c-about 1737 in St.Joseph-de-Chambly,PQ. He married a Francoise Valade-b-c-abt.1737 or so. Their child was a Angelique-Ursule Dussault that married Pierre-Benoni Gareau-St-Onge in 1777.
I need to find their parents and more on Pierre and Francoise Dussault. If any of this is in line with someones research please contact me via-e-mail at my address.
Thank you
Reni
