I'm doing my first novel based on true life. It involves a series of real family events that happened in the late 1700's and early 1800's and a mystery that developed then. The protagonist who now lives in Ohio, travels back to Morgantown, West Va to explore her roots and solve a family mystery. Should I use real names? The story is documented in newspapers etc. If I do, does that mean the family must be protected from any wrongdoing? Any ideas appreciated.
