Shaun

Shaun is an English spelling variant of Sean, which is itself the Irish form of John. John derives from the Latin Iohannes, which came from the Greek Ioannes, ultimately rooted in the Hebrew name Yohanan, meaning Yahweh is gracious. The name has been widely used in English-speaking countries, particularly popular in Britain and Ireland during the latter half of the twentieth century. Related forms include Sean, Shawn, Shane, and the original John.
