Editing Dylan ail Don (section)

==Genealogy==
In the Mabinogion, Dylan's mother, Arianrhod, is the daughter of [[Dôn]] and the sister of [[Gwydion]] and [[Gilfaethwy]]. Her Uncle, Math ap Mathonwy, is the King of Gwynedd, and during the course of the story, Arianrhod gives birth to her two sons; Dylan ail Don and [[Lleu Llaw Gyffes]] through magical means.<ref name=":1" />

In the [[Welsh Triads]], we are given a context for an actual Arianrhod who appears as the daughter of Beli Mawr<ref name="Bromwich">Triad 35. Bromwich, ''Trioedd Ynys Prydein'', pp. 284–285.</ref> and the sister of [[Caswallawn]] (the historical Cassivellaunus).<ref name="Guest, 1877: Ch. 9"/> Whether this reference is the result of the merging of a myth and history is unclear. It is possible that a later historic Arianrhod has become identified and merged with an earlier legendary/mythological Arianrhod.
