Meaning and history
Gladys comes from the Old Welsh name Gwladus, probably from gwlad meaning “country,” though it may also have been adopted as a Welsh form of Claudia. Saint Gwladus, or Gwladys, was the mother of Saint Cadoc and one of the daughters of Brychan Brycheiniog. The name spread beyond Wales after its use in Ouida’s novel Puck (1870).
Gladys moved from #830 to #967 for girls between 1997 and 1999. Its highest annual birth count came in 1920, with 8,819 births.
