I love
Artemis for a boy and I strongly dislike the spellings Artemas and Artemus, they don't look nearly as nice and they seem like they're trying too hard.
Artemis is technically feminine but it looks and sounds unisex and the
Artemis Fowl association supports that. Just because it was traditionally a girls name shouldn't keep you from using it for a boy. Names change like that.
we all share the same sky
