Robert Williams (Robert ap Gwilym Ddu)
From Wikipedia, the free encyclopedia
Son of William Williams, he was born at Betws Fawr in the parish of Llanystumdwy, Caernarfonshire. His father was a small freeholder, and he succeeded him in the occupation of Betws Fawr, moving, however, towards the end of his life to Mynachty in the same district.[1]
Williams was a home-loving farmer. A close friend and the bardic tutor of his neighbour David Owen (1784–1841) ("Dewi Wyn o Eifion"), he shared Owen's mistrust of the eisteddfod authorities of the day. He died on 11 June 1850, and was buried at Aber Erch.[1]
