Britannia Encyclopedia:

"Prince Madoc the Pilgrim (occasionally called Aeddan) was the son of King Sawyl Penuchel (the Arrogant) of the Southern Pennines by his first wife, the daughter of King Muiredach of Ulster [Ireland]. As such, he was brought up at his grandfather's Irish court where he became interested in the Christian religion. He was educated in Leinster before travelling across the Irish Sea to Glyn Rhosyn to study the scriptures under St. Dwei (David). He was later taught by St. Cenydd at Llangennith, and founded the church at nearby LlanMadoc on the Gower Peninsula."

"Madoc was well known for his kindness to the poor and often gave away his food and clothes to them while he himself lived on bread and water. Upon St. Dewi's death, he became the Abbot of Glyn Rhosyn, but later returned to Ireland to found famous monasteries like Ferns, Drumlane, Rossinver and Clonmore."

"He died in extreme old age on a visit to Mynyw (St. Davids) on 31st January 626. His body was taken back to Ireland for burial though. His relics can still be seen in Armagh Cathedral and in the National Museum of Ireland."

Surnames of Ireland:

"Maddox is derived from Mhaedog, a priest who was converted by St. David around Ferns in the 6th century. Large numbers of Madoc are seen in Wales from the 9th century on...they may have originated in County Wexford."
