Question for the Sindarin experts: is Meril still valid?

[Orphalesion]

^ Yup looked again myself (don't have the HoME anymore, lost all but the first two volumes :-( ) the name Meril for Gil-Galad's mother is not complete fanon, according to an old thread on Barrow-Downs it appears in the Quenta Silmarillion version as presented in Volume 5 of the HoME (the Shaping of Middle Earth) which, as far as I can gather from the names, seems to be very contemporary to the first edition of the Lord of the Rings.

In it Meril is the wife of Felagund and mother of Gil-Galad (and briefly of Galadriel and possibly Gildor).

So darn, it is at the very least, very very dubious if the name and word would have survived in Tolkien's final conception, which is a shame because even aside form providing another named wife, it would also provide an Elvish name for roses, which is always useful.
