Walton corresponded with the British novelist, essayist and poet John Cowper Powys for many years. Some of Walton's papers from 1936-1984—including biographic material, manuscripts and the correspondence with Powys—are archived in Special Collections at the Library, University of Arizona in Tucson. She was first cousin to Clifford C.

Furness edited and introduced a facsimile edition of "Leaves of Grass" (1939) and "Walt Whitman's Workshop: A Collection of Unpublished Manuscripts" (1928). A writer himself, Furness encouraged, inspired and mentored his young cousin Evangeline.
