I'm wondering about
Astraea too, now. I've always said it ah-STRAY-ah, but now I'm curious as to whether that's right or not.
Astraea's kind of like
Leo to me.
Astraea, the Goddess of
Justice, became the constellation Virgo after she left the our mortal world. So I prefer the name only on a girl who's actually a Virgo, even though not many people know of
Astraea's Virgo connection.
I don't think of the car when I hear
Astra, and I prefer it to
Astraea for a non-Virgo child. I also think
Astra fits better visually with your other female choices. I think it especially goes well with
Signy and
Sigrid in both sound and looks.
