Maybe you'll have better luck than me finding something about the early 19th century. :D The book I checked out only goes up to the Revolution, not that that's bad. (Although it really just ended up making me depressed, because pretty much most of the sources in there were [really disgusting] lesbian porn written by heterosexual males, making me realise that people do not change. Ah well, there was a scurrilous pamphlet from the Revolution with a list of notorious buggers, among whom was one Joly; clearly this is important.)
