For middle names we like slightly unusual names, something strong and from classic literature or mythology.
(think [name_f]Io[/name_f], [name_f]Juno[/name_f], [name_f]Athena[/name_f], etc.)
We found loads of these for boys, but good girls ones seem more difficult to find. Could you lovely nameberriers perhaps help us out?

Lots of great suggestions already. The only other I can contribute is una.
We have a Greek last name and the names [name_f]Daphne[/name_f], [name_f]Eleni[/name_f], [name_f]Thea[/name_f] and [name_f]Demetra[/name_f] always top our list. They have that “Greek” feel without being too far in left field.
[name_f]Xanthe[/name_f]
[name_f]Thora[/name_f]
[name_f]Calliope[/name_f]
[name_f]Clio[/name_f]
[name_f]Minerva[/name_f]
[name_f]Ziva[/name_f]
A name I have always loved is [name_f]Lucy[/name_f] [name_f]Athena[/name_f]. [name_f]Persephone[/name_f] is absolutely gorgeous, too!
[name_f]Andromeda[/name_f]. Such as strong name to me, and perfect for a MN.
