Image of John James and Mary Ann Sainsbury with others

Photograph showing the founders of Sainsbury's John James Sainsbury (front row, centre left) and Mary Ann Sainsbury (front row, centre right) outside a house.

It seems likely that the others depicted (or most of them) are Sainsbury's senior managerial staff - this appears to include some members of the family who were involved in running the company.

Some members of the family can be possibly identified: Arthur Sainsbury (furthest left), John Benjamin Sainsbury (row behind Mary, right of her), Alfred Sainsbury (furthest right, standing), and George Sainsbury (seated on right).

A note has been found written by an unidentified person which appears to relate to this photograph and identify some of the people:
