For those who have no idea what I’m on about, take a look at the link. (I wouldn’t normally post a link to Wiki as they’re decidedly anti-Cornish but this is all right on!)

An interesting article on Wikipedia. Just a thought, though. According to Nance’s dictionary, All Hallows Day was De Halan Gwav in Cornish. Is it possible that this became Anglicised to Halan Day, and eventually to Allan Day? Perhaps the connection with St. Allen, Bishop of Quimper, is later, established when the original connection had been forgotten.
