These three plays, 'Practice and Precept', 'Let Us Live' and 'The Firstborn' were written between 1914 and 1919 and are signed by 'D.V. Goode'.
Jacqui Deevy has identified D.V.Goode as probably Teresa's sister Josie, with whom she lived in Blackheath in SE London.
Josie was a very self reliant single career woman who worked all her life and retired as a former Domestic Science Teacher in Greenwich, London; in retirement she returned to Landscape in Waterford to live.
Josie was rememberd as being very interested in the Arts while living in London and would have had the opportunity to write also. We don't know for sure whether she was 'DV Goode', but my father thought it was a very plausible explanation.
