Who were Telphus' grandparents on his father's side?
Telephus In Greek mythology, Telephus ( ; Greek: Τήλεφος , "Tēlephos", "far-shining") was the son of Heracles and Auge, daughter of king Aleus of Tegea; and the father of Eurypylus. He was intended to be king of Tegea, but instead became the king of Mysia in Asia Minor. He was wounded by the Achaeans when they were coming to sack Troy and bring back Helen to Sparta.
Dalcassians The Dalcassians (Irish: "Dál gCais" ] ) were a Gaelic Irish tribe, generally accepted by contemporary scholarship as being a branch of the Déisi Muman, that became a powerful group in Ireland during the 10th century. Their genealogies claimed descent from Cormac Cas, who is said to have lived in the 3rd century AD. Their known ancestors are the subject of "The Expulsion of the Déisi" tale and one branch of their blood-line went on to rule the petty kingdom of Dyfed in Wales during the 4th century; probably in alliance with Roman emperor, Magnus Maximus.
