The funny thing is, even though pronouncing it with a z seems the most common and the most correct, I've never heard it pronounced that way, so maybe that's why it sounds weird to me. I've been trying to say it out loud to get used to the sound of it and try out the different pronounciations. At least we are already used to dd's name being pronounced wrong, so it will be nothing new. I say king Xerxes in the Bible with a ks sound, instead of a z sound, too, lol.
Dh had told me he got the name from a customer at work and then last night he was like, "Oh, I might have gotten it from X Men." I don't watch those movies, lol, so I never would have known.
