I don't know if this will help. It's the story of André Cummings from my grandmother's book about Sept Iles families. It references William and Anastasiaso I translated the text for you denby and there's a citation from Marielle Grenier a descendent who might know something. It's a long shot and overall maybe of more interest to Marie-France. Good luck.

At the outset, André Cummings worked at the whale oil extraction plant and later moved-on to the Clarke City Factory. To support his family however, André relied on transporting merchandise from between their arrival at the docks to the stores for the Hudson Bay Co. He also milled and sold wood to local natives.
His wife Alice was a well known seamstress who confectioned custom coats, pants and other clothes. She designed her own patterns. She was also very much appreciated for the cakes she baked for the local natives.
