Robert Ellis (also spelt Elis; 3 February 1812 – 19 August 1875), also known by the bardic name Cynddelw, was a Welsh language poet, editor, biographer, lexicographer and eisteddfod adjudicator. He was born at Tyn y Meini, Bryndreiniog, Pen-y-Bont-Fawr, in the historic county of Montgomeryshire in Mid Wales, where he initially worked as a farm labourer.[1]
His bardic name honoured the 12th-century poet Cynddelw Brydydd Mawr.
