So! According to the first paragraph, we have the following family tree:

Halavadar Dorlana, who once lived in Doriath, probably.

Their son, Ailwin Luvyre

His daughter, Y/N Luvyre.

Now, elves can quite happily have as many names as they like - but surnames? The only thing that comes close is House Finwe's use of the name, uh, Finwe. (It goes like this: Finwe had three sons. He called all of them Finwe, then added an extra bit to their names when he figured out their personalities: Curufinwe, Nolofinwe, Arafinwe. Then Curufinwe had seven sons, all of whom he called [something]finwe, including one he just called Curufinwe. At a later date, Nolofinwe and Arafinwe both needed to claim authority, so they augmented their names and became Finwe Nolofinwe and Finwe Arafinwe.) So technically Halavadar could have named their son Luvyre, added the Ailwin later, and Ailwinluvyre's daughter could have had the same treatment. But it's not likely.

As Doriathrin elves, all three should speak Sindarin, or at least Nandorin (closely related). How do the names shape up?

• HALAVADAR: actually surprisingly close! Hal+avad+dar is plausibly Sindarin, something like tall+reluctant+stop. It has a few too many As to sound properly Sindarin, though. "Tall and Unstoppable"?

• DORLANA: Dor+lann+a is probably the best parsing here: land+wide+from. It's an archaic form, but that's Doriath for you. I think it would actually be Dorlanna, but y'know, isolated people, variant spelling. "From the Wide Land".

• AILWIN: Not Sindarin, but I know where it came from. "Ailin" is a Quenya word for a lake, and in Tolkien's very early work, there was a Gnomish (proto-Sindarin) equivalent, "Ail". "Ailwing" is an attested Gnomish word, "Lake Foam", while Ailwin is Ail+win, lake+female, also in Gnomish. "Lady of the Lake". Not valid by the time LotR was written.

• LUVYRE: Cripes. Could just about also be Gnomish, Luv+yr+e - hanging+smith+[Sindarin] he, "dangling blacksmith". But even in Gnomish that would more likely be Luvur, and also NO NO NO. No elvish language would ever shove a -vyr- in the middle of a word. It's horrible and I hate it.

So I think they did use a wordlist, but it was one that presented all stages of Sindarin together, and they applied no thought whatsoever to the result. I should point out that there are later versions of most of these words - Luv+yr would be easily transformed into Glinga+tan = Glingadan and be relatively sound. (By what I think is fluke, none of their compounds run into consonant mutations, so they don't have to do what I did to get -dan on the end.)

The amusement value of Y/N having a surname meaning 'male smith', while her dad has a name meaning 'lake woman' is quite high, though.
