Voronwë called Nevrast 'the land of my birth' (in Of Tuor and his Coming to Gondolin in Unfinished Tales), so he must have born there before the exodus to Gondolin in I 126. He is last seen guiding Tuor to Gondolin in I 495, after which he makes no further appearance in any canonical work.

According to older traditions, though, he escaped the ruin of Gondolin and eventually sailed into the West, either with his friend Tuor, or even (in the earliest versions of the story) with Eärendil himself. Nothing of this has survived into the published edition of The Silmarillion.

Though Voronwë's mother is never named, we do know something about her. She was originally one of the Falathrim, the Grey-elves who lived along the coasts southward of Nevrast. She was also apparently of relatively high birth, being related in some degree to Círdan, the lord of the Falas.
