Ultan Patrick (Pat) Byrne (1901 - 1959) was a doctor and head of the laboratory staff at Essondale Hospital. This file contains Byrne's entrance, matriculation, and medical education certificates, a newspaper, and gas receipts. It also consists of photographs of medical association conferences as well as photographs of Byrne's spouse, Agnes, and children Beverlea Patricia May (Patsy) and Peter Ultan. The file also includes Byrne's discharge of duty certificate from WWII as well as his photographs of M Class Officers A22 RCAMC Camp Borden, one of which contains annotated names of officers.

The file contains a scrapbook created by Caunt for his daughter detailing significant moments of his medical career and personal life during 1934–1968. Photographs and newspaper clippings document aspects of Caunt and his wife Lucy's life at the doctor's residences and hospital buildings at Essondale; trips to Stanley Park; a celebration of the 1934 School of Psychiatric Nursing class with doctors and staff held at Dr. Arthur Crease's summer house in Ocean Park, Surrey.

It also depicts various events at Essondale Hospital including the installation of the Hospital's first television, the certification of Crease clinic by the American Psychiatric Association, occupational therapy displays, the installation of a new BC Tel telephone exchange, Christmas parties, retirements, events at Pennington Hall, and the opening of the Industrial Therapy Building. It also documents an event Caunt attended at the Chateau Frontenac in Quebec City held by the Canadian Psychiatric Association and events held at the Empress Hotel in Victoria.

A significant portion of the scrapbook documents the trips Caunt took in 1949-1950 to move geriatric patients to the new Homes for the Aged in Vernon (Dellview) and Terrace (Skeenaview). The scrapbook features photographs of settlements, including Terrace, McBride, Ocean Falls, Powell River, and geographic features including Lakelse Lake and hot springs, Gold Creek, the Inside Passage, the Lion's Gate Bridge, and Stanley Park.
