Effortlessly cool with a hint of the mystical, Phoenix rolls a lot of trends into one: it's a place-name and a bird name, it ends in the stylish letter x, it's got in-built nicknames, and it's unisex too. Familiar but not over-popular, Phoenix ranks in the US and UK Top 1000s.

One of the stellar unique baby names from mythology, Andromeda was the beautiful daughter of Cassiopeia who, like her mother, literally became a star--the constellation that bears her name.The Bohemian Andromeda makes a dramatic and adventurous choice in a time when four-syllable mythological names are gradually making their way into the mainstream.

J.K. Rowling is a modern master of naming who brought a whole constellation of ancient and celestial names to modern parents.

And the name Bellatrix is so closely associated with that character that it might be challenging to sidestep the association.
