Question for the Sindarin experts: is Meril still valid?

[Arvegil145]

Thank you for your substantial answer.

I DO realize that many of the names in the Lost Tales did not bear any meaning, or if they did little is known about it.

But if their etymology is obscure or nonexistent I would still like (since you appear to know much about the linguistic material) to have your advice on what names could be kept from Tolkien's early writings that do not contradict the later development of Sindarin or Quenya. For example (as I have written before):

- Gereth
- Evranin
- Nielthi
- Ilfiniol
- Tavrobel (studying its etymology, I have somewhat naively rendered it to "Taurobel")
- Bodruith
- Valwë
- Tulkastor
- Fankil
- Naimi

What do you make of these?

P.S. Could Voronwë in the later texts still have a son? It seems to me unlikely, but it might be possible (somehow).
