Meaning and history
Ena has several uses. In English it may shorten Helena, Regina, or names ending in -ena, each with a different origin. In Croatian and neighbouring languages it can be an independent modern name, while Irish Énna is traditionally masculine and unrelated in form. The intended meaning therefore depends on the bearer. Notable bearers include Scottish playwright Ena Lamont Stewart and Australian-American silent-film actor Ena Gregory. Exact source must be established individually.
Ena moved from #958 to #970 for girls between 1915 and 1920. Its highest annual birth count came in 1906, with 89 births.
