To me,
Chiara is a little bit boring because it's such a popular name. I prefer the variant
Clara, because it makes me remember Ancien Rome. The name
Chiara is used in Italy, and in Italy very few people bear a middle name. Maybe
Chiara Maria would work.
Maria Chiara is also quite popular.
Chloe is wonderful,
Fernanda sounds too elderly and severe, although I like the masculine
Fernando. Maybe
Chloe Fernande could be nicer.
Chiara's sisters' names are cute.
