This is a composite series of miscellaneous letters and copy letters between various other individuals, all of whom are connected to Wallace in some way. They include: some original letters, most of which relate to Wallace and were probably acquired by Minnie after his death; copies made by Wallace himself, presumably for his own interest; and typescript copies of other letters made either at the time or subsequently. Individuals represented include: Dr John Johnston; J.A. Symonds; Dr R.M. Bucke; the writer John Masefield; Wallace's cousins, Jim and George; Katharine Glasier; and the Ormrods. Many of the letters contain references to Wallace, including admiration for his exceptional personality and his work in spreading the word of Whitman.
Dates refer to the original letters rather than the copies which are generally impossible to date. All letters consist of one sheet of paper unless stated otherwise.
