There was certainly a Robinsons drapers shop in Hexham, in Fore Street, but it was at number 22/24 as far as I can see.
Did your Mary Ann and Mary Hannah live in Haydon Bridge in 1901 and did Mary Hannah marry Tom Ritson?
Do you know approximately when the photograph was taken?
It might be helpful if we could actually see the photograph – if I give you my email would you be willing to let me have a look at it?
