You are right about the Loon Lake Store formerly being the church connected to that cemetery. My Mom used to go to that church but I can't remember if it was Luthern or Methodist? Your best bet might be to contact the Historical Society in Lakefield as I'd bet they'd have a roster of the people buried there and maybe more info on that church. The boy scout who cleaned up the cemetery was one of the Temple boys but I can't remember which one. You could contact Mark or Ken Temple in Jackson and they might know.
