Oh wake up those sleeping ancestors. They could turn out to be your most interesting ones!
I woke mine up a few years ago going through FramilySearch.org (it’s free). My great-great-great grandfather and his brother fought in the siege of Ninety-Six (SC) during the Revolution. The brother was killed. Digging a little deeper I found they were Tories (Loyalists) fighting the American General Nathaniel Greene. Later this ancestor’s grandson fought in the Civil War in a Texas cavalry unit (CSA). These fellows kept on picking the wrong side!
