Ronan and
Maya could only have an
Iolanthe.
Lola is too show-girl for those distinguished, cultured parents.
Iona and
Malachi, on the other hand, feel like short and to the point types. Besides, another name from Greek history / mythology feels like overkill.
Iona,
Malachi and their son
Lin sounds perfect to me.
Amaryllis I've never warmed to much. It feels silly somehow, like
Marigold. I'd probably like it if I met one. But for now it feels unreal.
