The majority of this collection is correspondence between Annie Holiday Pelletier and her parents Elise and William Holiday. The collection also includes correspondence with and between other family members, photographs, genealogical and biographical information, and miscellaneous material about the Rondeau, Holiday, and Pelletier families. Included is an early written exchange, circa 1864, between Elise Rondeau and a local parish priest who disagree on religious freedom and the interpretation of a biblical passage. The correspondence between Annie and her parents, including the period in which she is a student at McGill, is written in French (from and to her mother) and English (from and to her father). This correspondence provides a vital resource on early student life and the day-to-day concerns of a young woman living away from home in late 19th Montreal. The correspondence is rich in its detail and frankness on matters of family life, conflict, and religious and educational issues.
