Thanks for clarifying.
Have to admit I wondered if I'd come across an early "Del boy"!
They probably were, but that was Minnie Bird, who also ran a green grocery. Joseph Bird, her husband and (great grandfather) was committed to Three Counties Asylum where he died in 1917. The 1911 census shows him at 33 Russell Rise. Three Counties has been a family secret, taboo and never discussed. I only discovered that when I began research, very recently. I hope to find out the reason for that committal, because he was a bit old for WW1. Thanks again for the info, very thoughtful of you.
