I wanna call her:
Aoibheann “eve + een” Eavan
aoibhinn ”pleasant, beautiful sheen, of radiant beauty.” Often interpreted as “little Eve.” One Aoibheann was the mother of St. Enda of Aran who died c. 530 AD.
It might sound odd to Russians (like Иван), but it should make sense for English speakers
Awesome that the image is already perfectly cleaned from background btw, it took me some time messing with (prolly) subpixels to get the witch pic to artifact-less level.
I'll try to finish at least the logic for her tonight...
Edit:
Another option:
Aine “awn + ye” Anya, Anna, Hannah
Ancient Irish name from the noun aine that means “splendor, radiance, brilliance.” Aine is connected with fruitfulness and prosperity. The queen of the Munster fairies was called Aine as was one of the wives of Fionn Mac Cool (read the legend). Aine appears in folktales as “the best-hearted woman who ever lived – lucky in love and in money.”
