Hello everyone and a massive thank you!
Sorry for the slow response, have had a hectic few days and haven't had a chance to look back at what you all have been doing. An absolutely stellar response and outcome.
The book identification provides a few small details which tie into the photograph - the book was published in Maryborough and Elizabeth Williams is buried in Bundaberg but had also lived in Maryborough where her daughter, Fanny Moore, lived. Elizabeth Williams died in 1911 and the book was published in 1894 so that gives the timeframe in which the photo was taken.
Thanks again everyone.
