Not to spark controversy, but I have a theory based on reading the will of Thomas Dunscombe (b. 1618 d. 1688). In his will prooved in 1688, he leaves a young negro girl named Susannah to his daughter Hannah and her husband John Richardson. Could this be the Susannah Dunscombe who marries Johathan Ogden in Rye, NY? Maybe she was a mulato. I am a descendent of Jonathan Ogden and Susannah Dunscombe and am also curious about the mystery of Susannah's parentage.
