  Research Notes:

From A History of Wales, pp. 78-79:

"A chain of marriages begins around 800 when Gwriad, a native of the Isle of Man, who perhaps had links with the Men of the North, married Esyllt of the line of Maelgwn Fawr; their son, Merfyn, became kind of Gwynedd in 825 on the death of Esyllt's uncle, Hywel ap Rhodri, the last of the male descendants of Maelgwn Gwynedd. Merfyn was the first of the lineage known to historians as the second dynasty of Gwynedd."

Esyllt married Gwriad ap Elydir of Man, son of Elidir ap Sandde and Unknown, about 800. (Gwriad ap Elydir of Man was born about 768 in Isle of Man (Mann) and died in 825.)
