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 item is an account book of Gabriel Switzer showing expenses and money received from 1883 to 1884. Also included is a list of officers and directors of the Emily Branch Agricultural Society, 1876.

The fonds consists of an account book of the general store of G.A. Gibson, Kent Street in Lindsay, Ontario for the period of May 1888 to December 1888; four diaries, May 1898 to July 1906, in which Gibson records the chores performed daily by himself and his family as well as money received (for the sale of produce) and money spent. The fonds also contains one additional diary, January 1910 to April 1914, which records chores and events on the farm. It is possible that the diary was written by Gibson's wife, Alice, but written as if Gibson had written it himself.

Collection consists of nine Boyd family photograph albums, 14 glass plate negatives, and several strip negatives. The images depict the lives and activities of the Boyd family of Bobcaygeon, Ontario, and include lumbering scenes, Trent Canal steamboats, buffalo/Hereford animals, and travel excursions. Also included are three "Gypsy" photographs (Peterborough, 1909), and photographs of winter sporting activities. Several photographs depict family members; many are unidentified. Also included in this collection are copies of the wills of WT.C. Boyd and Mossom Boyd.

This fonds consists of two certificates: a Horticultural Service Diploma dated 1952, awarded to Sheila Boyd by the Bobcaygeon Horticultural Society for "meritorious service to horticulture"; and, a Canadian Legion certificate dated 1955, awarded to Sheila Boyd as an expression of appreciation for her work with Bobcaygeon Branch 239.

The fonds consists of 25 black and white photographs of scenes, in and around Lindsay, Ontario, which cover such topics as parades and processions, military, industrial, social and family gatherings. The photographs were created by the Trotter family.

Fonds consists of 27 diaries of William Thornton Cust Boyd dated 1878 through 1917. Five of the diaries, 1884-1888, include financial records. The diaries recount the private and public life of Boyd, and include references to his wife, Meta, and their children, and social activities with family and friends including boating excursions and picnics. He refers throughout to Richard Birdsall Rogers (1857-1927), superintending engineer of the Peterborough Lift Lock, in social and business terms, and the two often conduct business relating to the Trent Valley Canal. Activities which Boyd participated in regularly include yachting and boating (on the "Calumet", "Ogemah", and "Ajax"), curling, hunting, gardening, tree planting, playing cards, skating, canoeing, and attending the theatre. He recounts details of the illnesses, deaths and funerals of acquaintances and family members, including his step-brother, Mossom (Mossie) Martin Boyd. Boyd recounts in detail the building of his house by John E. Belcher ([184-]-1915), architect, civil engineer, and surveyor. This house is now operated as Case Manor Nursing Home. The diaries speak of local and federal politics, World War I, and the activities of the church. They also detail the activities of the Lindsay, Bobcaygeon and Pontypool Railway Company, the Trent Valley Navigation Steamship Company, and the day-to-day operation of the family lumbering and cattle/buffalo enterprises.

Fonds consists of the wills of W.T.C. Boyd and Ida Lillian Boyd, with attached deed of Laurence Chadwick Boyd. Also included are several Boyd family photographs and one portrait. One of the albums has a photograph of Anne Langton, pioneer artist and teacher who settled in the Sturgeon Lake area, and whose journals have been published.
