1. Is it unusable (because it's a literary name)?
Can you picture a real person with the name?
Most definetly. I can picture it on a baby, toddler, child, teenager, and adult :)
2. Do you like it? Why?
Yes I like it! It has a nice sound, which always comes first for me, and it has a great meaning- which is like the icing on the cake!
3. Any mn suggestions?
