Edna f
Irish and English: in Ireland an Anglicized form of EITHNE (SEE Eithne), and probably of this origin in England too. However, the name also occurs in the Bible, in the apocryphal Book of Tobit, where it is the name of the mother of Sarah and stepmother of Tobias. This is said to be from Hebrew 'ednah rejuvenation, pleasure, or delight, and if so it is connected with the name of the Garden of EDEN (SEE Eden). It does not occur in the Hebrew Bible or Old Testament, although the variants 'eden and 'adnah occur as male names. The earliest known uses of the given name in England are in the 18th century, when it was probably imported from Ireland, rather than taken from the Bible.
