First Lady Michelle Obama always suspected that she had white ancestors. But she had no idea who they were. With DNA testing and research, I was able to solve that mystery and finally identify the white forbears who had remained hidden in her family tree for more than a century.

 All across the country, growing numbers of people are turning to DNA testing as a tool to help unlock the secrets of their roots, using companies such as ancestry.com, among others. When I started researching my new book, “American Tapestry: The Story of the Black, White and Multiracial Ancestors of Michelle Obama,’’ I pored over historical documents that I found in local archives, courthouses and libraries as well as records that I found online on ancestry.com and other state and local databases. But I knew that DNA testing would be the only way to unearth the truth.
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.)

 This was painful news for many of the Shields descendants. They knew that that Melvinia might have been raped and that their kinship originated during slavery, one of the darkest chapters of our history.

 But last month, members of both sides of the family – black and white — put aside the pain of the past. They got together for the very first time in Rex, Georgia at a ceremony to commemorate Melvinia’s life. They swapped family stories, posed for photographs, exchanged phone numbers and had a meal together.

It was something to see.
David Applin, who is Melvinia’s great-grandson, said the reunion was “wonderful.” And Jarrod Shields, who is the great-great-great grandson of Melvinia’s owner, described it as a day “my family will never forget.”
