As an aside, South Pembrokeshire has been English speaking since 1100 when Normans populated it with Flemish settlers. There seems to be an insidious attempt to Welsh-ify the area in recent years. Witness the ridiculous attempts at trying to give Cresselly a Welsh name, and a bilingual sign for Narberth, by dropping off the N to create Arberth......
This IMO is just as bad as English folk populating Welsh speaking areas and expecting everyone to speak English.
Tin hat on.
Our local Council (note we are deep blue with over 55% Welsh speakers) are having fun with Beaumaris.... now nobody knows where it is
