Llŷr

Llŷr (Welsh: Llŷr Llediaith (Welsh pronunciation: [ˈɬɨːr ˈɬɛðjaiθ]); Lleddiaith meaning 'half-speech'[2] or 'half-language'[3]) is a figure in Welsh mythology, probably originally a deity, probably derived from Irish Ler ('the Sea'), father of Manannán mac Lir.

[4] Other than his progeny and odd tidbits, his identity remains obscure.

Llŷr appears as the father of Brân, Brânwen and Manawydan by Penarddun in the Branwen, Daughter of Llyr, the Second Branch of the Mabinogi.

(*) Unbordered names are figures not in Llŷr's line of descent, though perhaps members of the extended family.

But Bromwich observes that Penarddun should be emended to being the sister of Beli, which would bring consistency with statement elsewhere that Caswallawn and Brân are cousins.
