If there had been no "title" on the back this view of a garden, with a large house in the distance almost concealed with trees, would be difficult to place and date as Frederick Downer was already a photographer in 1871 through to the 19th century.

However Judge John Theophilus Rivaz retired to Watford some time between 1871 (census) and 1878 (trade directory). He lived in Watford Place and died there in 1882. (See here for detailed family history information). This suggests the picture is of

The Garden at Watford Place

circa 1880
