I've always loved traveling through Salem - and no, I'm not lost, there is a Salem, Connecticut. Of course, that may have something to do with ice cream. (For non-locals, Salem Valley Farms makes very good ice cream!) However, Salem has a much more complicated history, which you can read about on the town's website.
In the meantime, if you have ancestors from Salem, you have options. The Salem Historical Society is only open a few weekends a year at their house museum in the center of Salem Village. However, a phone call never hurts. Contact information can be found here.
