Actor and writer Ruth Jones confesses to a passion "to share the wonderful characters in Wales" and she finds several in her own family tree.
On her mum's side, Ruth discovers Welsh mariners who travelled the world. On her late dad's side, Ruth learns that her grandfather Henry Richard Jones was a leading figure in the Medical Aid Societies of South Wales, a forerunner of the NHS.
Ruth discovers how her granddad's work led him to lobby the Minister of Health Aneurin Bevan - a fellow Welshman who became known as the father of the NHS. Locally, Ruth's grandad was remembered for his devotion to his fellow men and women.
