One thing isn't completely clear to me: at this point, where Finwe is wed, are they still at Cuivienen or already on the Road or already near or in Beleriand?
Morwe and Nurwen still confuse me, I have understood that they are not meant to be the two Avari leaders from PoME but entirely different characters, however still weird that Morwe had interests in Miriel (that destiny thing i already mentioned, though you assured me that Nurwen and Elwe are "just friends").
Considering Eöl, in the PubSil he's a Teler but as far as I can remember Tolkien changed his concepts over the time... at first I think he was an Avar, then a Teler and finally he discussed him eventually having been a Tatyarin-Avar (means one of the Avari-Host that was clo0sely akin to the Noldor, hence his smithing Skills and friendship to dwarves all of which sound more like a Noldo than a Sinda).
