Hefin

Somewhere between Kevin and Heaven lies summery Hefin, a sunny yet rugged choice, totally different in feel to its aforementioned sound-alikes. In Wales, it is given to a small handful of babies most years, though in recorded history, it has never been given to more than six in a single year.

Hefin derives from Haf, the Welsh word for "summer", though this form likely derived from a manuscript by the 18th-century poet, antiquarian (and occasional forger), Iolo Morganwg who came up with the phrase Alban Hefin ("summer solstice"). It may also have been inspired by the Welsh month name, Mehefin, translating to "midsummer" and used for June.

Pronounced HEV-in.
