Thanks for your response suepp. Yes that is the same Thomas Smith you have mentioned. His father was also called Thomas and his mother Mary Ann, she used to sell fish from a barrow on the quay and around Conway Town. When I first started using this site I found a photograph of her on here, selling fish outside Dunphy's at the honey fair.
It was after he left Conway and moved to Llandudno when he was in his 30/40/50s I was looking for. I have had one response from another site and they thought he had worked as a coal man and lived on West Shore, but I'm still not sure if that was him.
I will have a look at the 1929 directory, thanks for mentioning that it is very much appreciated.
Kind Regards,
