I saw the headline and immediately thought ‘I feel I should know something about this name’. So I looked into my Norwegian name sources and found nothing, but when I looked into Norse mythology I found what I was looking for!
At first I thought I’d confused it with Disa which is an old Norse name meaning ‘goddess’ but I found Eisa as well!
Eisa was the daughter of [name]King[/name] Logi who was either a personification of fire or the handsomest, largest and strongest man because he was descended from giants (which was a good thing).
Her name means ‘glowing embers’ and she and her sister Eimyrja were considered the fairest women in the land
I think that plus the dance connection makes Eisa the coolest name I’ve come across in a [name]LONG[/name] time!!!
She goes on my list, now!
[name]Edit[/name]: And if I remember correctly, you have some Scandinavian heritage which just makes it even better, right?
