Think first! My name is Tamzin (not as unusual as some, but pretty unusual at the time I was a child - it was years and years until I met another) and I do like an unusual name now I am an adult, but found it difficult as a child.
Unusual can be lovely, but do your child a favour and pick a name...
....that they won't have to be spelling out for everyone every time someones asks for their name.
....that people can pronounce easily when they read it written down (poor, poor children in some of my classes who lament that they never have their name said properly).
...that isn't so unusual that no other children have ever heard of it...so unusual in fact that it gives the horrible high school children who have never met you before an easy excuse to laugh at you- personal experience speaking here :(
