The following tintype photos have been collected from various members of the Dickinson family. Collectively they appear to be from the same time period and some appear to be in the same sitting.
We know Harry had a brother named William Henry Dickinson, who appears to have been named after their father, William Dickinson of Sheffield. (Harry subsequently named his eldest son William Henry Dickinson as well).
Harry Dickinson is shown alone in two of the five photos, and with his older brother, William, in two of them. In one, however, Harry is shown with a young man who we have yet to identify. If anyone has information, please comment below.
