My understanding is that the photographic studio of Townsend Duryea in King William Street, Adelaide was destroyed by fire early on the morning of Sunday 18 April 1875 after operating there since April 1855 causing the loss of many historical photographs and records.
The photograph below is connected with the Browning family of which she was presumably a member. However, I am yet to identify her.
Does anyone know whether the number on the back "20079" can be of help to me in identifying/dating this old lady who I think may have been born before 1800, and almost certainly was living in South Australia.
