Llyr Llediaith. (Llyr Lleddiarth, King Lear, Lear II, Tasciovanus, Half-Speech) Said to be the son of Baran, or of Ceri. Llediaith is said to mean “the act of speaking Welsh with a foreign accent,” thus the name "Half-Speech." He was educated in Rome by Augustus Caesar. His home was at Dunraven Castle, which was situated on a hill called Twyn Rhyvan (the Hill of Rome) located in Glamorgan. Probably the same as Leir of Britain.
The name Manannan derives from an earlier name for the Isle of Man, and his patronymic mac Lir was metaphorical and meant "son of the sea (Ler)": his father is given in early genealogies as Allód.
He is unrelated to the character Lir of the well known story of the Children of Lir.
In the Isle of Man, Manannan mac Lir was known as Mannan.
Lir, overwhelmed by the kindness of the man he had insulted, accepted, and made haste to Lough Derg, arriving the following day with a retinue of fifty chariots.
Lir chose Aebh, because she was the eldest, and they slept together that night.
Lir came south to take her; they slept in Bodhbh Dearg's palace; and then he took her back with him to the Fews.
