This fonds consists of records encompasing three generations of the Boyd family of Bobcaygeon. The fonds has been divided into the following series: photographs and glass negatives; Reverend Henry C. Avant; Mossom Boyd; Mossom Martin Boyd (Mossie); Lillian de Grassi Boyd; the De Grassi papers which are records of Dr. Alex De Grassi, Lillian Boyd's father, a physician from Lindsay, Upper Canada; Gardiner Cust Boyd; Mildred Boyd; Winnett (Brownie) Boyd; Laurence Chadwick Boyd; Mossom de Grassi Boyd; A. Sheila Boyd; stamps; artifacts; business which deals with the Boyds interests in lumbering; agricultural papers which deal with the Boyd's farming interests in buffalo and cattle; and, estate papers. The strength of this fonds lies in its completeness. Nothing was thrown away and there are grocery lists, laundry lists, staff salary books, furniture receipts, party and wedding invitations, school report cards, ship and railway timetables, diaries and approximately 20,000 pieces of correspondence. This has resulted in a remarkable record of a large household from the 1880s to the 1980s and an invaluable source for social and business historians.

This fonds consists of oral history tapes made by George Cobb. Topics covered on the tapes include: Trent Canal, lumbering, early medicine and dentistry in Peterborough County, Indigenous history and culture, mills and so forth. Fonds also includes tapes made by Cobb of other broadcasts and recordings (located at the end of the list). Browse file list for more information.

The fonds consists mostly of Helen Marryat's (nee Helen Fowlds) personal experiences as a nurse in World War I, and her activities as a local historian. There are clippings of her articles in local newspapers, historical maps (drawn by Gerald Marryat) and other materials relating to settlement of Hastings and district such as education and nursing. Also included are the correspondence and photograph collections of her brothers, Donald and Eric (mostly from World War I), and material on Frederick Marryat (1792-1848), navy captain and novelist. In December 2001, Trent University Archives launched an online exhibit which depicts Helen Fowld's experiences in World War I. All her letters and diaries are transcribed and are found at the following site: http://digitalcollections.trentu.ca/exhibits/fowlds/ffowldswelcome.htm
