Bébinn
Bébinn Bé Binn, is an early Irish name applied to a number of related and unrelated figures in Irish mythology. In some sources Bébhinn ( old orthography: Béḃinn) is a goddess associated with birth and the sister of the river-goddess, Boann. Bébinn is also described as being an underworld goddess in both Irish and Welsh mythology, inhabiting either the Irish underworld Mag Mell or the Welsh Annwn, although it is unknown which is the original source.
