My mother - who's family was from the Pontlliw area - called her 'Betsi Bwt' and named her doll in her honour! (Circa 1925 - And I still have Betsi)

Our chorus went:
O mor drwm yr ydym ni (X 2)
Ac aeth Bet i mofyn sebon
Ar ôl claddu'r mochyn du.

I found this lovely discussion while checking the words for a handwriting competition -

Diolch!
