Errdil

From Witcher Wiki

Errdil - an elf living in Rinde. Prior to the short story The Last Wish, he'd moved in together with his quiet, taciturn wife and cousin Chireadan, and had also bought an inn, intending to renovate it.

He recognizes Dandelion, claiming he saw the bard, once, singing in the court of king Ethain of Cidaris.

[edit] In The Hexer TV series

Jacek Radziński played elf Errdil in the episode 11, Jaskier, and 12, Falwick.

It's uncertain whether these elves share anything but name.
