Milena (Mirena/Malaena)
Greta (is it pronounced GrEta or GrEEta? I say the former. Don't really want confusions over pronunciation, if possible)
Helena (again, is it HelEna or HelAyna. I say the former but...)
Lousia (OK but a lot of similar letters to DDs name and is it really OK to have 'Lou' as a NN?!)
Am I being too silly worrying about pronunciation. Does it matter? I mean, people would know once they knew, wouldn't they... ?
