I've always considered 'Middle-earth inspired' names for my future children (yes, creepy me intends to have children someday). I mean, why not?

I've also considered quite a few Roman names...
Here's some random names...if they even remotely appealed, I took note of them... On some of them I wouldn't go with the traditional spelling, but... is that illegal?
Girls:
Tiriel (I like Miriel too)
Aerie
Rían
Rómenna
Silme
Serindë
Aerin
Vala
Vána
Boys:
Daeron
Dáin
Rodyn
Tarcil
Tárion
Either:
Enyd
Sirith
Teiglin
Estel
And my boyfriend swears his first son is going to be named Ecthelion...
I would prefer Aetius, personally...
