Great photo, thanks. Your memory throws another question into the works. By 1907 Robert Young was in Leeds opening another shop, then he moved to Normanton and settled there and raised his family. As far as we knew the Stirling shop was then nothing to do with him but if the name stayed perhaps other family members were involved. If so it would also explain why the son of a farmer took up a career in drapery.
Do you have access to any trade directories that would give the owner's name by ant chance?
