The Wichita Eagle reprinted an interesting article from the Kansas City Star about some genealogists who solved a riddle that more mainstream historians hadn't resolved (not clear whether the historians couldn't solve the riddle or just hadn't bothered.) Benjamin "Pap" Singleton was born a slave, escaped to freedom, and was instrumental in encouraging former slaves to move to Kansas and other states to escape the Jim Crow south after the Civil War. The riddle? What happened to him after his prominence faded? Some Kansas genealogists and historians found his death certificate and cemetery records.
It's an interesting article that gives genealogy a positive shout out. Read it here.
