The First Lady's great-great-great-grandmother, a slave called Melvinia, was made pregnant in 1859 at the age of about 15 by Charles Shields, one of her owners' sons, according to a comprehensive new book.

Shields, who was about 20 at the time, was a descendant of Andrew Shields, a protestant Irish immigrant who fought against the British in the American revolutionary war in the late 18th century.

Mrs Obama was not aware of the family tree uncovered by the book's author, Rachel Swarns, who also alerted a series of white cousins around the US to their genealogical link to the White House.

Swarns, a New York Times journalist, said several black descendants were concerned Melvinia had been forced into a relationship with Shields.

White descendants said they hoped that was not true.

So both Barry and Michelle are White folks with Black ancestry?
