(f) An ancient and once common Irish name,
phonetically spelt as Oonagh or Oona. Uny is another Irish form,
which perhaps explains why Winny, the pet
form of Winifred, was often used as a substitute for it.
Others took the name to be the same as Unity, one of
the Puritan abstract-quality names. Agnes was also thought to
translate the name, in the belief that Una derived from Irish
uan, ‘lamb’ and that Agnes also meant ‘lamb’
(‘lamb’ in Latin is agnus). The original meaning of
the Irish Una is in fact unknown. It is not the same name as Spenser’s
Una in the Faerie Queene(159o, 1596), where the Latin feminine
of unus, ‘one’ is clearly the intended meaning. Una
continues to be used to some extent in Scotland. There is a character
bearing the name in Scott’s Waverley (1814).
