Fonds consists of sheet music, some of which is hand-copied. The items originated with Captain Charles Rubidge and penciled annotations suggest that he collected or hand-copied a number of them in the early 1800s for his wife-to-be, Margaret Clarke, before coming to Canada. "Mrs. Rubidge" is written in hand on some pieces. Provenance is indicated on some documents in layered notes made by family descendants across generations. Also included is information compiled by Laurie Lambe Wallace about the sheet music and its history within the Rubidge family.

In 2017, 29 additional pieces of sheet music dating to the early 1800s were added. This music belonged to Mary Catharine Dunsford, wife of Reverend Hartley. Some of the music includes handwritten notations with family names and dates. While the publications of some pieces may date to the early 1800s, the handwritten penciled dates cover a period generally between the 1830s and 1860s. The notations point to connections between the Rubidge, Dunsford, McEwen, and Boyd families of the Peterborough area. Included in this addition is genealogical information compiled by the donor.

She mentions by name individuals who can sing old songs brought from the old country, or songs learned in the lumbering shanty and carried down from generation to generation.
