I am currently working on a novel set back in 1850, and one of the characters is going to be from New York City. I was wondering if anyone here happened to know what the well-to-do, wealthy neighborhoods/parts of town in NYC were back then. To give context, the character is telling someone that he has a house in the city, and I'd like to be able to state a specific neighborhood as the location of the house. Any assistance that you could provide would be greatly appreciated! Thanks so much!
