I suspected that Mrs. Obama’s white ancestors belonged to the white Shields family that had owned her great-great-great grandmother, Melvinia Shields. So I persuaded several descendants of the black and white Shields to do DNA testing.
The results showed that the two families were related. The DNA testing indicated that Melvinia’s owner’s son was the likely father of Melvinia’s biracial child, Dolphus Shields. (Dolphus Shields is the first lady’s great-great grandfather.)
