Ithel or Idwal ap Morgan was a king of Gwent and Glywysing (i.e., Morgannwg) in southeastern Wales.
His father was Morgan the Generous, the probable namesake of the later realm of Morgannwg (whence modern Glamorgan).[1] Ithel seems to have inherited his father's realm intact, but then divided it among his many sons: Ffernfael in Gwent and Rhys, Rhodri, and Meurig in parts of Glywysing.[1]
