Names starting with E

Names starting with E for both boys and girls, ranging in popularity and style. From classics like Edward to modern names like Everly.

The straightforward Erica is a Norse feminization that was long associated with the complex, mega-popular character Erica Kane, played by Susan Lucci for decades on the soap opera All My Children. Used in Scandinavia since the early eighteenth century, where it was usually spelled Erika, it was in the Top 50 girls' list in the USA in the 1970s and eighties.
 It is worth noting that Erica is also a flower name, in which sense it is its own name, rather than a feminisation.
 The most prominent bearer of the name in recent times is novelist Erica Jong, author of the influential Fear of Flying.

Erica

Popular in Ireland but less familiar elsewhere, Eimear is a mythological choice, which some may see as a fresh alternative to Emma. 
 
In Irish legend, Eimear was the wife of the warrior hero Cuchulainn. She was said to possess the six gifts of womanhood: beauty, voice, speech, wisdom, chastity, and needlework. While the exact meaning of the name is unknown, one suggestion is that it means "swift, quick", from the Irish mear.
 
Pronounced as EE-mer, the name may also be spelled as Emer, and more rarely, Eimer. Other forms are Éimhear (said as EH-ver) and Eimher, the Scottish variant (pronounced AY-veer).
