Comments for the name Jaxson

A cousin of mine just had a baby boy, and named him Jaxson, this spelling. The name itself I'm all right with, but I find the 'x' followed by the 's' to be redundant. "Jax" (what they call the baby) already covers the 's' sound, but then they stuck another 's' in the name. And Jaxson is in the top 200 boys' names! I don't get it.

Jackson is a perfectly fine name and this is a perfectly horrid spelling of it.
