Gaynor
An Irish surname often explained as a form of Guinevere or a related Arthurian name, though some scholars treated it as uncertain.
The #5,505 most common surname in the United States (2010 Census) — about 1 in every 48,868 Americans shares it.
Etymology
The name is most often connected with the medieval French/Welsh Arthurian name Guinevere, which appears in later English forms such as Gaynour or Gaynor. Early surname writers also linked it with “the son of Gwenivere,” treating it as a patronymic or derivative of that name. Because the historical evidence is thin and some sources disagree, the exact origin is best treated as uncertain, with an Arthurian personal-name connection the strongest traditional explanation.
History
The name is well attested in Ireland, especially in counties such as Mayo and in Irish surname studies, where it appears alongside related forms like Gainer and Gaynard. English-language antiquarian sources also noticed it as a surname form of the Guinevere tradition. In modern use it is found both in Ireland and in the wider English-speaking world.
