Gutyn Ebrill was the bardic name of Griffith Griffiths, who was an Arch Druid in Patagonia.
Gutyn Ebrill (Griffith Griffiths, 1829-1909) established the Gorsedd of the Bards in Patagonia. Caeron (W.H.Hughes) and Prysor (William Williams) held office after Gutyn Ebrill but they considered themselves to be vice-Archdruids, under the authority of the Archdruid of Wales. After Prysor died in 1945 it seemed likely that the Patagonian Gorsedd would disappear for ever. Then, at the beginning of the twenty-first century during Meirion's period as Archdruid it was revived and representatives began to attend the National Eisteddfodau and Gorseddau of Wales once more.
