what kind of luxury car would a family in the 1920s have -- particularly a family that retained a chauffeur? would a studebaker be appropriate? if not, what kind of car would they use?
Is there a 'typical' Japanese surname that might be assigned to someone who had none? I'm not interested in the legality of this (my situation is pretty unorthadox) - I've just got a character and the authorities in the story would need to assign her a surname for the purposes of alphabetization. In England it would be quite likely she'd be called 'Smith' - is there a similar, very common surname in Japan?
