'Our main sources of information on this architect came from the autobiography written by his younger brother who, at age 93, recorded his own career, and the career of his brother Charles, the architect. This document is now in the possession of his daughter Mrs. Helen M. Hoyte of Norfolk, England. Her letter to us was sent to us in May 1987. Other information came from the Glenbow Museum in Calgary, and from the Canadian Architectural Archives at the Univ. of Calgary. The daughter of Charles Hay, Mrs. A.M. Sweeney of Santa Rosa, Calif. also provided information to us in 1987.'
