I like
Saffron.
Serge just sounds like surge or like a serger.
Edina and
Magda are cool 'older' names.
Catriona,
Fleur, and
Sarah are nice.
I like
Oliver too.
Jackie is fine on a boy but dated on a girl.
Patsy and Bubble are dumb,
Mo is too short to sound like anything without a long full name.
Justin is dumb/dated and
Marshall is approaching that but not too bad.
