Natasha is expecting a boy to join big sister Margot and is looking for suggestions.
We're both keen on Aubrey and may well end up using it, although considered using this for a girl and slightly concerned many may see it as a girls name.
Other possibilities are Eliot, Dorian, Sebastian (although there are lots of little Sebastian's about), Rory, Rufus, Felix, Ambrose.
Names I like but Dad has rejected: Emmet, Edmund, George (very common) and Gregory."

I love the refined and elegant vibe with a quirky twist that the names on your list have. Hopefully, the suggestions below suitably emulate your already-fabulous list.
Bastien – If Sebastian feels a little too common-place, how about the slimmed-down French short form Bastien? It currently ranks in the French top 100, and easily works for English speakers. Bastian is a variant spelling.
Alban – Mixing the sounds of Aubrey and Sebastian, Alban is a Roman name used in the Middle Ages thanks to the eminent 4th century British saint. It feels both modern and ancient at the same time, and has the bonus of being in good use in France (currently ranking #154).
Crispin –A dignified Roman name with a medieval heritage perfectly summing up the refined-yet-quirky vibe. Cris is an obvious nickname but I love the idea of the nickname Kip or Chip.
Cyrus – With serious cool-factor, Cyrus is a stately gem that was once born by great Persian kings.
Tristan – A heroic Arthurian name with a strong Celtic past and has good use in France. It peaked at #47 in 2001 in France (currently #139).
Bertrand – A bilingual French and English name with an ancient Germanic heritage and refined medieval style.
Ralph – A genial and sophisticated name with Viking heritage and medieval style.
Raphael – Currently super-popular in France at the moment is the cultivated biblical choice, Raphael. At #235 in England and Wales, Raphael is uncommon but also recognisable with sophisticated style.
Barnaby – A name that can be both playful and polished in equal measure. Barnaby is a historic name with plenty of charm and familiarity.
Augustin – This French form of elegant medieval Augustine (ranking #48 in France) has a cool effortless style in English.
Thaddeus – A quirky biblical name with a strong artistic streak. A rare yet recognisable name with history.
Hector – A mythic hero whose name has echoed down the ages. At #255 in England and Wales (and #261 in France) it is uncommon but not outlandish.
Evander – A cool ancient Greek name (meaning "good man") which wears well in a modern world.
Linus – Another sleek ancient Greek name from mythology which feels both cool and quirky at the same time.
Lionel/Leopold– Two lion-like names (though the latter is actually Old German for "bold man of the people") which are familiar but a little bit different. Lionel was in the French top 100 from 1933 to 1989 while Leopold was in the French top 100 up until 1923 and is now seeing a small revival.
Ewart – The gravitas of Stuart combined with the airiness of Ewan. Ewart is a Norman form of Edward, which was made famous in the 19th century by Prime Minister William Ewart Gladstone.
Quentin – A quirky Norman name borne by a French saint, sounding both modern and antique at the same time.
Victor – Ranking at #28 in France, Victor is a solid old-timer that is poised for revival.
Gideon – A heroic and handsome biblical name which is familiar but strangely rare in use.
Xavier – An exotic, stylish saintly choice with a fashionable 'x' and superhero edge.
I hope this has been of use. Good luck with the name choosing!
