Have you read Neal Stephenson and Nicole Galland's The Rise and Fall of D.O.D.O.? It has a cute take on witchcraft in the same time and place (among other times and places).
And to you and others who are relatively new to AW - please come hang out with us in the Historical Writing area of the Share Your Work forum (password vista).
Me - I am still stuck in NYC ca.1950. Even with the novel fairly stalled out, I'm working on a short story there. Truthfully can't imagine writing in a different historical era; the amount of research it takes to be comfortable writing in one era is staggering enough!
So true. My knowledge of the eras I write in are essentially a lifetime's worth of reading about these particular times, visiting sites, and seeing pictures. I've attended or watched dozens of talks about the Civil War, for instance, and read a score or so books on Lincoln alone, and visited, er, a dozen or so CW battlefields, not to mention visited tons of historic homes and towns. Oh, and I've read plenty of literature from the time, too. The point is, I just know things, and I don't necessarily know how I know them; I picked it up somewhere along the way. Sometimes it isn't even facts as much as a feeling--"no, a person would not do that or think that way in 1860".
I'm not quite as comfortable in the 1900s-1910s but have been interested in the period most my life, between the Titanic and the last Romanovs. So I'm familiar and settled there, but it isn't quite home like the Antebellum/CW period.
