Sunday morning, people come back to Gatsby's. New rumors circulate – that Gatsby is a bootlegger and that he is the nephew of German General von Hindenburg (a successful military commander in the war).
Nick makes a list of the people who came to Gatsby's parties that summer. There are East Egg names that sound very WASPy, West Egg names that are distinctly more ethnic-sounding (with clearly German, Polish, Irish, and Jewish names featured), and a bunch of theater names who connect back to the idea of Gatsby as a theater producer.
One morning in July, Gatsby picks Nick up in his beautiful car and takes him to Manhattan for lunch.
They don't have much to talk about, but suddenly, Gatsby tells Nick to ignore all the rumors about him – he'll tell him the real deal. According to Gatsby, he was born to a wealthy Midwestern family, his parents are dead, and he was educated at Oxford per family tradition.
