Maelon is a character in the Welsh legend of St Dwynwen: http://en.wikipedia.org/wiki/Dydd_Santes_Dwynwen 'mael' is apparently from a proto-Celtic word meaning prince - see Mael. I'd pronounce it more or less like MY-lon. It's not in use in Wales. I could find only one use of it as a name in the birth records, in 1902.
