Crown Fit for a King

I have a really big head canon about the royal family of Greenwood the Great, so I'll leave this here. I especially have a lot of thoughts about Thranduil's wife, even though we know absolutely nothing of her. But my biggest struggle for the moment is her name - not only there are very few nandorin words known, but the sindarin variant sounds so strange (if I go for the meaning that I want) and over the top for a common nandor. Sure, she would probably use a sindar name eventually, esp. after marrige, and it could sound complex... But uuuuugh, lady!
