Thomas Jones is my great great Grandfather and he mostly lived in Rhyd y Foel, Llanddulas (Llandulas), North Wales.
I haven't been able to track down his birth certificate, although I've found lots of babies born in 1843 named Thomas Jones (checking both Holywell registration district and St Asaph registration district).
Depending on which census you look at, he could have been born in the following places: Gwaenysgor (Flintshire), Alltmelyd (Allt Melyd, Flintshire), Llanefyd/Llannefydd (Denbighshire).
He was a Limestone Quarryman and married Eliza Williams in 1867. I think his parents were William and Anne/Annie, but not sure.
Some other relevant keywords: Abergele, Ty Moel, Bodlondeb, Penporchell.
Here's a news article about him from the North Wales Weekly News of 2nd April 1909:
'Liverpool Weekly Post' merit medals have been won by Thomas Jones, Bodlondeb, Rhydy-foel, Llanddulas, aged 66 years, quarryman.
Hearing that two children aged 3.5 and four years had fallen through the ice in an old clay pit near Rhydyfoel, he ran to the rescue, and without taking any clothes off pluckily jumped into the water, and after some difficulty brought both children out alive.
