Though rarely heard today, Coy has been around for a century and was not that uncommon a hundred years ago. There have been a couple of NFL players named Coy, Coy Bowles is in the Zac Brown band--and of course there was Coy Duke in 'The Dukes of Hazzard.'
Not a particularly recommended choice, due to the flirty, feminine connotations of the word coy.
