Eva: gravel-voiced Viennese WW2 refugee who smokes like a chimney, wears Chanel, and listens to Shostakovich for pleasure. Delightful, frail, occasionally completely terrifying.
Jasmine: pretty, not bright, perfect handwriting, pink bedroom. Possibly picks nose.
Scarlett: (in the days before la Johansson, probably an very old ex-flapper who wore too much makeup and was smoking buddies with Eva) nice public-schoolgirl, a bit naive, beautiful and talented. Dad's mates ask each other if she's legal yet. Scarlett is definitely far too nice to have the faintest idea what they're on about.
Esme: the older sister of Eva?
Tristian: a lost cause if parents don't spell it "Tristan". Otherwise, Tristan Farnon comes to mind.
Charlie: cute. snub-nosed, rumple-haired, inquisitive. (good name this year - possible future famous scientist?)
Sebastian: aesthete. Too gentle for the world. Aware that he can't live up to Bach.
Finley: small northern irish ratbag with a cheeky grin. Terrible in class. Probably grows up to be a highly successful and serious barrister and has kids called Jasmine and Tristan.
Xavier: see Sebastian but perhaps substitute Baudelaire?
Joshua: sweet and stolid. Good at school, 2:1 at uni, nice job, nice wife, nice house.
