I was a little confused when I couldn't find it under unisex. I'm a boy who was born with this beautiful name. But for anyone who wants to name their child Anu it is in fact a unisex name, but it's also quite a pretty name. It rolls off the tongue and is pleasing to the ear. I do find that most people only know one Anu if they know one at all. I looked at the other Anu and I do feel that they should just be blended into one because it's the exact same, I have a Finnish unisex name, not a Near Eastern Mythology boy name. Sorry if I wasted your time.
