Elva a Swedish name? It's very rare here, I've never met one. Probably because it means "eleven" in Swedish. I don't know if it even should be listed as a Swedish name.
I did have a relative called
Elvan ("number eleven"), though - she had ten siblings - but it's even rarer.
Does the sea exist
Because of our longing?
