Gladys

From the Old Welsh name Gwladus, probably derived from gwlad meaning "country". Alternatively, it may have been adopted as a Welsh form of Claudia. Saint Gwladus or Gwladys was the mother of Saint Cadoc. She was one of the daughters of Brychan Brycheiniog. This name became popular outside of Wales after it was used in Ouida's novel Puck (1870).
