It's amazing what a phonecall can produce. It turns out George C is correct. My Mum was given a photograph after I asked her to speak with my aunt.
Now it turns out she did not know who he was, but his name was George. However, when Johns daughter Alice died, she had several pictures on the wall of George, he would have been her Grandfather. Those pictures will be in my possesion soon.
She also said, he had a studio in Gateshead, this would explain why one of his children was born in Gateshead.
