History of Lovecraft Country

So I'm writing a short story set in Lovecraft Country in the 19th century, specifically when Andrew Jackson is still president. The setting is a town like Innsmouth, a fishing village with some occult practices. I'm wondering, what would society look like at that time? For instance, would the Deep Ones like Andrew Jackson, or would they be missing John Quincy Adams? I also know that during this time there was a moral panic about Freemasonry and other secret societies. Would this town be concerned about the panic, or would they be leading the charge? Would there be a divide between those who mated with the Deep Ones and those who didn't?

I think they would probably vote for Kang and Kodos as third party candidates.

As I recall, the Deep Ones didn't seem too concerned about being discovered, as much as they disliked outsiders in general. Besides, a seaside colony of fishmen is too left-field even for a paranoid witch-hunt. Finally, the town was pretty uniform with just about everyone being a descendant of a Deep One, so there would probably be no trouble in that regard. Live and let dive, I say.

That's funny. You know, a thought popped into my head a while ago: Lovecraft Country is basically what Lovecraft thought of rural New England. He portrays them as superstitious, degenerate, and in some cases they're inbred monsters. It's a straw man of everything he thought was wrong with the "country folk". With that in mind, what would it look like if Lovecraft decided to flesh out the history of Lovecraft Country?

I'd imagine a small scale version of how Assassin's Creed fleshed out the history of the world. It'll be all conspiracies and secret supervillains in cahoots with bizarre aliens. Still, a good place to start looking for inspiration would be Robert Howard's Solomon Kane tales, which delve somewhat deeper into world-building and connections with existing mythology. Essentially, it's the Cthulhu mythos seen through the eyes of someone who isn't a paranoid racist - Kane even has his own magical black best friend... sort of.

Lovecraft focuses more on the emotional aspects of the setting; Howard is the one to look for regarding details of the setting itself. All in all, sure is helpful that there was a whole writing circle all exploring similar ideas in one of the first shared universes in modern literature.
