I really love this name.
It's not that popular (I have onyl heard of two in the whole of this area, know one well
).
Means "rich war", excellent! Good strong name, also like the fact that it ends in neither ie (as in Maisie, Daisy, Milly) nor a as in Olivia, Amelia, Melissa etc) so that sets it apart somehow.
People always seem to post on MN that it's very very popular but honestly, apart from Fivegomad I really know very few (and I don't know fivegomad but YKWIM.
It was also the name of the last English queen - Edward the Confessor's wife. And Harold (killed at Battle of Hastings) had a mistress called Edith Swan Neck - just a bit of history for you!)
