This foundation stone is set into a building at one end of Princes Street, Cork. I never
noticed it until the day I took this photo and a quick search for Barbara Jessie Burton returns information and pictures of foundation stones laid by her in
the years following 1927:
Vauxhall Gardens, UK (PDF)
stone2 Aldershot, UK A comment on Streatham Elephants mentions her too.
Does anyone know anything else about Barbara Jessie Burton?
