Chicago question

[ffutures]

Quick question for anyone who knows the history of Chicago - need the name of a reasonably well-to-do district at the end of the 19th century. My first thought was Grosse Point, as in Grosse Point Blank, since I somehow got the idea it was an upper-class suburb, but on reviewing it I'm not sure that's correct. Anyone got any suggestions? Want somewhere where a slightly crackpot religion appealing to the well-to-do might be based.

Later edit: Someone has very quickly pointed out that Grosse Point is Detroit, not Chicago. Shows how well I remember films! This pretty well has to be a BIG city e.g. Chicago, possibly New York or Boston, I think Detroit is too small in 1895.

Thanks, any alternate suggestions will be appreciated.
