I see from the Alberta Map Chinook and Cereal are about 10 kms apart. Then I see from the AGS Homestead index, Salve Trygstad's Homestead was on Section 24, Township 27, Range 07, West of 4th Meridian.
So it seems to me all these places are within about 10 or 15 kms east of Youngstown.
Have a look here,
