The bulk of the fonds is the correspondence of Carrie and Julia. Of particular interest is their letters from Lady Agnes Macdonald, widow of Sir John. Baroness Macdonald's letters tell of her life abroad with her daughter Mary and her continuing interest in Ottawa life. There is a small amount of correspondence from Miriam Reiffenstein Macpherson Fenwick, the daughter of Miriam Reiffenstein Macpherson. Besides legal papers, such as wills, administration of trustees and estates, the fonds reflects important happenings in the life of the Reiffenstein family; the fire at the family home in Ottawa in 1885, Carrie's train trip West with the MacDonalds in 1886, a family trip abroad in 1889, the diamond wedding anniversary of George and Georgina Reiffenstein in 1900, and the trip to England in 1904 by Carrie and Julia where Julia died in London.
