Pierre-Georges Roy, archivist and historian, was born in Lévis, and educated at the Séminaire de Québec and Université Laval. He began working as a journalist for the Canadien and the Quotidien but at age 20 had founded his own historical review, Le Glaneur, and went on to found the Bulletin des recherches historiques in 1895 (which published until 1968). He then worked at the federal archives in Ottawa until he was named chief archivist for Quebec in 1920. Having created the Archives nationales de la province de Québec (now known as the Bibliothèque et Archives Nationales du Québec), he was awarded the title of Knight of the Legion of Honor in 1927; in 1931, he was appointed curator of the Musée provincial which originally housed the Archives nationales (now the Musée national des beaux-arts du Québec), a post he occupied until 1941. He received the Royal Society of Canada’s J.B. Tyrrell Historical Medal in 1932, as he continued to write hundreds of books and pamphlets on Quebec history.

James Roy was an Anglican clergyman who served in Montréal, Ontario and New York State.

Gerry L. Roy was born in New Brunswick and studied pre-engineering at St. Francis Xavier University in Nova Scotia before obtaining his B.Eng (Civil) at McGill in 1952. He spent 3 years as a field engineer on the construction of oil refineries, including the Petro Fina refinery (now Petro Canada) in Montreal.

Roy went into consulting engineering with a small Montreal firm, eventually becoming partner. For a year he was in structural and municipal design before moving on to project management. Roy managed the design and construction supervision of the new towns of Port Cartier, Gagnon, Wabush and Churchill Falls. He managed major infrastructure works of Expo '67 and the cities of Riyadh and Medinah in Saudi Arabia. Roy participated in several joint ventures including those that established concepts for Mirabel Airport and Nuns' Island and the design and construction of the Abu Dhabi International Airport. He also led the preparation of numerous feasibility studies on a variety of projects. In later years he devoted much of his time to marketing his firm's services in Canada and abroad.

Gerry L. Roy retired in 1987 and remained active in community activities and in the St. Francis Xavier and McGill Alumni Associations.
