Vita reminds me of the British writer
Vita Sackville-West. I think her full name was
Victoria. It has an arsty, intellectual vibe that I dig. I never knew it was derived from
Vitus. Thanks for the new knoweldge. :-)
Vida is nice too. It reminds me of
Matthew McConnaghy's (sp?) dd
Vida. They named her for the Spanich word for life, which I thought was pretty sweet.
If I were choosing between the two, it would depend on which vibe I wanted: Northern European, crisp
Vita or Mediterranean, sultry
Vida. I don't know if you have different ways of looking at the two so I can't really say which is better for you. For what it's worth, I can see both
Vita and
Vida fitting into your spunky sibling set quite easily.
