Thanks Mike, I think you're right. I'm guessing the photo dates from the 1910's, maybe as late as the early 1920's. In 1920 my Griffin ancestors were at 2 back of 34 Stour Street, having moved a few doors up from 31 since 1911, with other relatives by marriage the Patricks at No.37, so I'm presuming it's one or other of the families.
