With regards your search for info re McCormick -Mary Guichon was still alive and living in Calgary when she phoned me about 2 years ago now.You could probably contact her via the Riley and McCormick shops in that City.One at the International Airport and one in the City.
My great uncle Hugh McCormick went from Cushendun Nth Ireland about 1920s to Calgary also and was an Accountant to Eneas in the Company.I am trying to trace a brother also Michael McCormick who went along also. They had no family. maybe we could be related?
Their father was Michael McCormick and mother Rose{ McNeill} and they lived on the Torr Rd,Cushendun
