Hi Philip
I’m really pleased you found your Grandfather’s birthplace, what a shame (as is normally the way) the house itself has gone.
Last week I visited birmingham to see a relative who is now living in a care home. I realised I was just a road away from where Mom and her family had lived at the start of the War. This house is still there, and it was a funny feeling to think of them all there living their lives. I stood there - discreetly - looking at the house wishing if only I had a time machine to go back to 1939 and be able to see my lovely Mom as a young girl!
