Who Are the Ancestors of Joseph Mitchell from Quyon Quebec Canada

Hello,

We are trying to find any information for our maternal great-grandfather. His name was Joseph Mitchell, baptized on May 7th, 1890 in Quyon, Quebec, Canada. In 1909, he married Elizabeth Beauchamp (Eliza) in Ste-Cecile-de-Masham, Quebec. We are trying to trace our Scottish-Irish roots. Any info. would be greatly appreciated. Thank you!
