Jane Johnson, my 4th GGrandmother, b. abt 1813 in Missouri, married a Cape Girardeau, MO. physician named William Shaw. I have a clear, documented line from Jane Johnson to myself. I suspect that the Jane Johnson who married William Shaw was the daughter of Preciller (Priscilla, Precillia) Johnson, emancipated slave and common law wife to John Edwards, but cannot prove it. Any assistance in proving, or disproving, my suspicion would be much appreciated.
