Odd First Name

[stormdog]

I've seen a lot of unusual first names working in tech support and in geneaology. Today, though, I saw one I've never seen before. The father of the person I'm researching is named Xury. I've confirmed the spelling on several documents. He was born in Ohio in 1858. The census says his ethnicity is White. It looks like his father was named Joseph and died in the Civil War. I have no good guess as to where that name comes from. Any ideas?
