Ari- wonderful, singer Nico's son. Also name of character in Royal Tenenbaums. Personally I don't like short names that sound like nns but apart from this is fab.
Levi- fabulous, one of my top choices
Sebastian- like, quite normal now actually.
Crispin & peregrine- are quite hilarious. no. imho.
Inigo, Dexter, Julius- meh.
Octavia- my name. Please do not use if you are not actually very very posh as people assume you are. also not very easy to go do a job like carpentry or something similar if thats what your dc so desires. prescriptive & aspirational depending on if you're landed gentry or not.
Ivy, Tabitha, Juniper, Zara- love.
Claudia- Schiffer.
Isis, Ione- hard to pronounce
Millicent- smells like wee. bit prissy on the tongue. also i know a little milly who hates her name.
Juno- film. teen preg.
Lois- american housewife.
