Eithon is Hebrew, Welsh in Origin.

Eithon is a rare Welsh masculine name of Celtic origin, most plausibly connected with the hydronym Ithon, a river in Powys. The name appears in medieval Welsh materials in place- and personal-name contexts, though it was not common as a forename. Its exact meaning is debated; some link it to Welsh eithin “gorse,” evoking rugged, heathered landscapes, while others see it as a traditional river-name of obscure Celtic root, suggesting imagery of swift, clear waters rather than a literal translation.

As a given name, Eithon has seen sporadic revival in Wales and among the Welsh diaspora from the 20th century onward. Variants and related forms include Ithon (spelling variant), Eiddon (a cognate medieval name), and the modernized Eithan; Ethan is a popular look-alike but derives separately from Hebrew Eitan “firm, strong.” Modern feminine adaptations such as Eithona or Ithona sometimes appear in contemporary usage.
