I had a bit of look and noticed you said this in a previous thread regarding names:
All I care is that our child will be able to find their name on one of those novelty number plates! Also so they wont have to spell it for everyone and that people who see the name can distinguish between Male/Female ie not unisex.
Your child will have to spell his name for everyone, and having any other spelling than Xander (which is pronounced Zander so will cause confusion if you want it pronounced any other way) is going to have people guessing the gender, because it's essentially made up. Anyway, just food for thought. Your child, your choice of course
