Hi !!!!
One of my favourite names is
Serena while the Italian for the mythological creature is 'sirena' (for both 'siren' and 'mermaid').
So it is too similar to be considered.
In the other side I would love Siren because of its wonderful sound that make me think of
Serena.
It would be a circle.
Anyway I would prefer it spelled Syren / Syrena. I don't know why because I generslly dislike creative forms but this time I find the y very elegant in this name.
WDYT?
