In Maryland (United States) A grave was found with the remains of slaves who worked in the furnace of a foundry ago 200 years. Now, an investigation has achieved an important achievement: establish a kinship between 27 slaves and 42,000 Americans.

One of the researchers who has contributed his bit to this achievement is the Spaniard Íñigo Olalde, who explains that the DNA of these slaves “cannot be deleted”. “They wanted to restore a bit of the memory of these communities of African slaves whose history has been somewhat erased,” he explained to laSexta.

Despite spending two centuries in the United States, the African-American population did not appear in the census until 1870, seven years after the abolition of slavery in the country. Beyond that year, they could not trace his family tree.

Comparing the DNA of the slaves with a database of millions of people, they have discovered that they came from various towns in Senegal, Gambia and Central Africaas well as with paternal ancestry from England and Ireland.

“Historians know that much of these relationships they were forced relations between white men and their African slavesOlalde added.

It is a unprecedented research who, for the first time, has been able to draw direct family connections between the present-day black population of the United States and their slave ancestors. They have only analyzed the DNA of 27 slaves, but it could be the first page of a story.
