Historical information
The inscription on the back of the photograph indicates that it is of Chris Stratton, his brother Bill and his mother.
This is most likely Christopher John Stratton, 1862-1906. His mother Johanna (née Bentley), widowed in 1863, married Archibald Ferguson shortly afterwards, and the "brother" is likely to be Archibald's and Johanna's son William John Ferguson, born 1866. Chris Stratton also had a son named William John, born 1894.
