Here are a couple of names of genealogists involved in the family tree analysis:
“Two of the most historically significant African Americans in the history of our country are amazingly directly related,” said Ancestry.com genealogist Joseph Shumway in a statement. “John Punch was more than likely the genesis of legalized slavery in America. But after centuries of suffering, the Civil War, and decades of civil rights efforts, his 11th great-grandson became the leader of the free world and the ultimate realization of the American Dream.”
Ancestry.com called on a past Board for Certification of Genealogists president to perform a third-party review of the research.

“A careful consideration of the evidence convinces me that the Y-DNA evidence of African origin is indisputable,” said Elizabeth Shown Mills in a statement, “and the surviving paper trail points solely to John Punch as the logical candidate.”

That John Punch ancestry has been stretched to infinity; like a rubber band, it’s ultimately going to snap. He’s now an ancestor of Ralph Bunche, the winner of the Nobel Peace Prize for 1960 as Palestinian Mediator, the sister of Loretta Fuddy (by marriage) and the man with the unknown ID in the WH.

He’s like vegemite. A little goes an awfully loooooooooong way. (Chickensh+t has the same attribute.)

and how is John Punch related to Joseph Kearney?

“A careful consideration of the evidence convinces me that the Y-DNA evidence of African origin is indisputable,” said Elizabeth Shown Mills...

So, what you said about him being Irish is bogus?

but of course, once again, you have absolutely nothing that links him to this person either.

Two scholars dispute assertions that a 17th-century forebear was one of the first documented slaves.

As professors of history and African-American studies at Boston University, we have been unraveling the story of the first African arrivals in Virginia over the past decade, and despite suggestions to the contrary in the New York Times article, we can assert that Africans were not indentured servants as Europeans were....

The Times article also mentioned that Punch had a DNA haplogroup common in the Cameroon. We consider this extremely unlikely. Our research shows clearly that the overwhelming majority of Africans brought to America on Portuguese ships before 1640 were enslaved in Angola. At that time, there was no slave trade at all from Cameroon.

John Punch, therefore, was likely an Angolan, not a Cameroonian.
