Monday's episode of Who Do You Think You Are? featured Ruth Jones, best known as the actor and writer behind the Welsh-based TV shows Gavin and Stacey, and Stella.
Probably unsurprisingly, Ruth's family was primarily Welsh - although most people from South Wales in particular have some English ancestry somewhere along the way.
The part of the family we followed with this episode, though, were Welsh through and through.
Encompassing both rural, and, more extensively, maritime Wales, Ruth's episode showed how much coal permeated through the Welsh economy in the 19th Century.
Moving on from there, the episode looked at Ruth's ancestor's connection to the Welsh medical societies that acted as a fore-runner to the NHS, and correspondence between him and Aneurin Bevan himself.
All in all, it was a sturdy little episode comprising the penultimate offering of this small series.
A brief reminder that Saturday (31st October) is the last day to get in touch with me for Christmas 2020 orders.
