Sadhbh

Meaning — From the Old Irish "sadb" meaning "sweet" or "goodly". In Irish mythology, Sadhbh is the mother of Oisín: she was transformed into a deer by the Dark Druid Fear Doirc and returned to human form when she entered the protection of Fionn mac Cumhaill. Their son Oisín ("little fawn") was born while she was again in deer form after she was recaptured. The name carries both gentleness and the tragedy of transformation.·Old Irish origin·Female·SIVE (rhymes with "five")

Characters with this name are often at the centre of stories about love separated by circumstance, about the cost exacted by those who cannot bear to see goodness flourish freely.
