Griff is my cousin. He would have been born about 1939. His mother was my father's sister. She was married to a Morgan James and died in 1966. I met Griff once only when I visited Dowlais with my family - 15 April 1950 - when he taught me how to draw a Spitfire.
I believe Griff remained in Dowlais and married a lady named Lilias who had a hairdressing salon also in Dowlais.
If Griff or any of his relatives is interested I can offer quite a lot of information going back to 1847.
