The Thomas Henry Mitchell's of Stoughton, Sask. Canada

I am searching for the Thomas Henry Mitchell familyof my Father's side from where I grew up in Stoughton, Sask. Canada area during the 1930's and anyone connected to my Father's family. Thomas Henry Mitchell was born in 1909 and was the 12th child in the family of Robert William Mitchell & Margaret Miranda Cowan union.
My Mother's name was Agnes Amy Blaylock born in 1915,who came from Creelman, Sask. Canada. My Mother's parents were John William Fraser Blaylock from Cockermouth, England, and Florence Densley from Wallsal Staffs, England. I would appreciate any info on either the Mitchells or Blaylocks to have accurate statistics.
