Ceinwynn is Welsh in Origin.

Ceinwynn is a modern, Anglicized elaboration of the Welsh name Ceinwen/Ceinwyn, built from cain or cein (“fair, beautiful, gentle”) + gwen/-wen (“blessed, white”). As such it conveys the sense “beautiful and blessed” or “fair, blessed one.” In traditional Welsh morphology, -wen marks the feminine and -wyn the masculine, but contemporary English usage treats spellings like -wynn as stylistic rather than grammatical, making Ceinwynn a rare yet feasible choice for girls or as unisex.

The root appears in the cult of the 5th–6th‑century Welsh saint known in English as Saint Keyne, whose Welsh name is Ceinwen; churches and wells in Wales and Cornwall preserve her dedication. The name resurfaced with the 19th–20th‑century Celtic Revival and now occurs chiefly in Wales and among diaspora families. Variants and cognates include Ceinwen (traditional feminine), Ceinwyn, Ceinwin, Keyne, Keyna, and Keina; diminutives may be Cein or Ceini.
