The sitters are identified by a pencilled inscription in a period hand on the reverse of the mount, reading Charlotte Kennard / and Ethel May / my godmother / 1867

This is probably the Charlotte A. Kennard who, according to the 1861 census, was living at number 37, Porchester Terrace, which would have been the house across the road from Silvy's studio. Her father, Robert Kennard, was an 'Iron Master'. At the time of the census, Charlotte was twenty-four years old and unmarried.
