[5] As a child she enjoyed watching the local dances[6] as they were performed in an open space below Twyn Chapel in Caerphilly[4]: 32  and at Nantgarw and Y Groes Wen.

The rise of Nonconformism in Wales meant that by the time Catherine Margretta Thomas was in her teens folk dancing had practically been eradicated in Nantgarw.

But the influence of Nonconformism waned and by the time Ceinwen Thomas was attending school she was discussing the tradition of dancing in Nantgarw with her mother.

[6] After Ceinwen Thomas had left college she met Walter Dowding of the Welsh National Folk Dance Society.

[11] Welsh dancing is an integral part of both the local and national eisteddfod tradition in Wales.
