Thanks to a BBC Wales programme, he traced his family back on his father's side to 1760, with ancestors working in lead mines and his great-grandmother a servant for the Mostyn family. His great-grandfather was a Methodist minister.
Jones's wartime memories included being taken to a field near the family home in Dolwen Road during the war by his brother.
"He told me that a bear lived in the brook at the end of it so I ran home and didn't dare go back," he said. "I can also remember the thrill of seeing a tank driving up the road with these enormous searchlights."
He met his father - a bank clerk - for the first time on the platform of Colwyn Bay railway station when he returned from India after serving with the RAF during World War Two.
He said he always felt "very Welsh" despite his mother being from Bolton and his parents moving to Claygate in Surrey when he was five years old.
"I bitterly didn't want to leave and hated being transported to the London suburbs," he recalled. "I always regretted that and was always saying 'I'm Welsh'."
