King of Nargothrond

From Tolkien Gateway

King of Nargothrond was a title begun by Finrod Felagund, who founded the citadel and realm of Nargothrond in West Beleriand. After his loss, the Kingship passed to his nephew Orodreth, who held that title until he perished in the Sack of Nargothrond. If this title had survived, Gil-galad would have been next in line, being the son of Orodreth.
