In the marriage register for 1850 for Panteg/Panteague (near Pontypool), there is a record for the marriage banns of Phillip GILBERT, miner, of Cwm, son of John GILBERT, miner, and Elizabeth DAVIES, otp, daughter of Thomas DAVIES, founder.
It seems Cwm is an abbreviation, but which is the most likely town?
Thanks for any help - I'm half a world away from Wales, and am clueless on the local geography.
