Yeah sorry, I'd overlooked your 'tongue in cheek' comment to
Hui above. But I still think
Findaráto as a Mother-name for Arafinwë is untenable. On the other hand I could imagine Eärwen calling her hubby thus, and their children using the Sindarized form when talking to grand-uncle Thingol and his people.
By the way, if Felagund was renamed
Inglor, what does that mean for
Gildor Inglorion? Was he literally Felagund's son?
I rather liked the bit about Felagund not marrying because he foresaw his oath to Barahir and its fatal consequence (also Amarië).
That's the thing about Tolkien - you can't change a name without changing the story.
