Children Beuno | ||
Bugi ab Gwynlliw Filwr (also Hywgi, Bywgi and Beugi) was a Welsh Christian saint in the 6th century.
He was reportedly the son of Gwynllyw, a Welsh king, brother of saint Cadoc and the father of Beuno (died 640), abbot and saint. His wife Peren, Beren, Pherferen or Perferen was the daughter of Llawdden Llydog or Lleuddun Luyddog, identified as King Lot of Lothian.
It is reported that when Bugi was dying he sent for his son Beuno, who came to him, and "After receiving the communion, making his confession and rendering his end perfect he departed this life." It was said that Beuno planted an acorn at the site of Bugi's death, which grew into an oak tree forming an arch; any Englishman passing through this arch would die, while a Welshman would be unharmed.
