In October 1920, Enid McGregor (b. 1889), the youngest sister of author Gertrude MacGregor Moffat (1884-1923), wrote a description of Wallingford Hall, the women’s residence at McMaster University, which had opened the previous month. Enid, who graduated from McMasters with a BA in 1912, was Librarian and a Reader in English there for many years, and had been part of the creation of Wallingford Hall; she is almost certainly one of the women in this photograph.
