The place you are looking for is actuallly Cote d' Midi, St. Andrews East, Quebec. I was in St. Andrews this summer
trying to do some research on my McLean's and Camerons. It seems now that Cote D'Midi is actually a road in St. Andrew's that you can locate by looking for Chemin Cote d' Midi. It is a road that ends at a large expanse of farming land. I will have to go back and check with the town hall and see what historical information they have on that location.
