Gustav Felix Adam's Three Contemporary Anglo-Welsh Novelists: Jack Jones, Rhys Davies and Hilda Vaughan (1950) was the last critical analysis of her work for some time and not entirely complimentary.Thomas 2008, p. 19. In Glyn Jones's The Dragon Has Two Tongues (1968), considered a seminal analysis of the tradition of Welsh literature in English, Vaughan gains only one mention, as one of those who "write about the squirearchy and its anglicized capers." A major contribution to her legacy was Christopher Newman's biography of her published in 1981. He remarks, "Her claims to be remembered... are two: first [that] she extended the English regional novel to the "Southern Marches", the land [known as] rhwng Gwy a Hafren; secondly, that in doing so, she made a significant addition to Anglo-Welsh writing."Newman p. 79. In the 1980s and 1990s, Vaughan's work became reincorporated into a renewed analysis of Anglo-Welsh writers and writing.Thomas 2008, p. 20.
