James Patrick Howley was born on July 7, 1847, in Mount Cashel, St. John's, Newfoundland.

He was a naturalist and geologist. He was educated at Saint Bonaventure's College, St. John's, Newfoundland. In 1867, he entered the service of the Newfoundland Government as a clerk in the office of the Colonial Secretary. His work as an assistant and then as Director of the Geological and Topographical Survey of Newfoundland between 1868 and 1909 produced much of the scientific basis for understanding the geography of the island’s interior, geology, and mineral deposits. He became interested and studied the indigenous people of the island of Newfoundland Beothuk. Upon retirement in 1909, Howley lectured, wrote, and represented the colony overseas as the recognized authority on its geology, mineralogy, natural history, geography, and human history. He is regarded as the creator of the institution that became the Provincial Museum of Newfoundland and Labrador and served as its first curator. In 1915, he published the book "The Beothucks or Red Indians - The Aboriginal Inhabitants of Newfoundland" which remains an important source on the Beothuk, whose last member, Shanawdithit, had died in 1829. His never published memoirs "Reminiscences of Forty-two Years of Exploration in and about Newfoundland" have been made available as digital documents.

In 1874, he married Elizabeth Jane Firth (1851–1935). He died on January 1, 1918, in St. John's, Newfoundland.

Francis Lamb Howland was born on December 13, 1842, in Whitby, Durham, Ontario.

He was a physician and civil servant. He graduated from McGill University’s Faculty of Medicine with honours in 1867. He practised for a short time in Woodstock, Ontario, and in 1875, he moved to a small community in Huntsville to become the village’s first doctor. Shortly after his arrival, he founded a newspaper named The Liberal. As its editor, he exercised considerable influence in local politics and was successful in petitioning for the extension of the Muskoka Road north of Huntsville. His most important effort for the future growth and development of Huntsville was in persuading the Grand Trunk Railway to route the railway through Huntsville. He served as reeve in 1889, 1890, 1893, 1895, and 1896 and as mayor of Huntsville in 1904.

In 1870, he married Jennie Huggart (1851-1916). He died on November 8, 1916, in Huntsville, Muskoka, Ontario.

F. S. Howes was born in Paris, Ontario. After serving as a signaller and wireless operator in World War I, he entered McGill University, graduating with honours in electrical engineering in 1924 and earning an M.A. in 1926. Howes then went to Imperial College of the University of London, where he received a Ph.D. for a thesis on the subject which would be his life-time research interest, acoustics. He joined the staff of McGill's Electrical Engineering Department in 1929 as a Lecturer, rising to the rank of Associate Professor in 1946 and Professor in 1956. Besides teaching courses in radio engineering, radar and related topics, Howes organized evening graduate programmes in engineering; this activity led to his appointment as Director of McGill's Extension Department (1949-1960). Howes also acted as a consultant to government and industry on acoustical, radio and television problems and to McGill and Sir George Williams Universities on sound levels in buildings. He succeeded in incorporating a sound-proof (anechoic) chamber as an acoustic laboratory into the design of the McConnell Engineering Building. Finally, Howes campaigned for collective bargaining rights for engineers in his capacity as chairman of the Canadian Council of the Institute of Radio Engineers (1948), and he helped to organize the CAUT and MAUT, serving as president of both bodies. He retired from McGill as Emeritus Professor in 1964.

William B. Howell was born in England and educated there and in Montreal, where he received his M.D.,C.M. from McGill University in 1896. He practiced in Montreal, and during the First World War he worked overseas with the Field Ambulance Service. In 1918, he was appointed as the first full-time anesthetist to the Royal Victoria Hospital. Howell retired to England in 1937, where he pursued his avocation in literature and history. He was the author of a history of medicine in Canada (1933) and of a biography of Dr. F.J. Shepherd.

Thomas Frederick Gilpin Howell was born on June 30, 1837, in Clapham, Surrey, England.

He moved to Montreal in the 1860s, and is listed in "Wilson’s New York City 1868/1869 Copartnership Directory" in a partnership "George M. Haywood & Thomas F. G. Howell." In the 1870s and 1880s he again resided in England.

In 1866, he married Jessie Rennie Leach (1842–1917). He died on May 10, 1889, in Montreal, Quebec.
