This was the true name of the Grey-hammed Lady who, in an Irish romance, married King Arthur when she took him and his men to the Otherworld. She was the daughter of DAIRE (Daere in Welsh legend), a fairy king, by Rathlean. She was said to have appeared from time to time as a deer.Possibly from Dún Ailinne, the name of an ancient fort on top of a hill known as Knockaulin near Kilcullen, Co. Kildare, Ireland. Dún Ailinne is now thought to have been the seat of the kings of Leinster. The mythical Leinster king Find File is thought to have lived here, and may have given his name to it.
