Hello! re: DRISCOLL's in Canada in 1800's - I recommend that you search in the province of Newfoundland & Labrador, Canada. This province was known as Newfoundland during the period of your search.
You could search the following sites that offer great information & links: Newfoundland Grand Banks - ngb.chebucto.org and Newfoundland-Canada GenWeb - nl.canadagenweb.org. Area names/towns etc..the capital city of St. John's and area; Conception Bay South/Bell Island/Lance Cove/Kelligrews/Topsail, etc..; Conception Bay Centre - Holyrood; Harbour Main (Gaskiers); Chapel's Cove; Lakeview; Avondale (Salmon Cove); Conception Harbour/Cat's Cove/Bacon Cove/Kitchuses and Colliers. Also, search Conception Bay North - Brigus; Cupids; Bay Roberts; Spaniard's Bay; Port de Grave; Carbonear; Harbour Grace...Bay de Verde/Western Bay & areas.
