"KayNoel - the only reason I like Kay on a boy is because of Sir Kay in the Arthurian Romances."I think this isn't the Welsh name Kay but the variant of Kai which is pronounced KYE and male ;)
LOL. I don't KNOW if it is a variant of Kai, I just assume that it is because Kai is fairly common in Germany while the Welsh Kay (or Cai) is not. But if the Welsh Kay is the only one you like, we'll just say it's Kay ;)
