My guess is yes...Zavia is the feminine form of Xavier (according to the site) and Xavia also looks like a feminine form of Xavier. By the way, I am liking this. I love Xavier but have way too many boy names, but this is a name I can add to the girls list.
Zavia doesn't do much for me, but it's not bad. I would say Zavia like (ZAY-vee-ah), but I would Xavia like (eks-AY-vee-ah) or (ZAY-vee-ah), depending on my mood, lol.
