Genetic Analysis Suggests Columbus Had Tie to Nobility

Christopher Columbus' origin story has a new genetic twist—this time pointing not to Genoa, but to Galician nobility in Spain. A study says DNA from descendants buried in a Seville crypt suggests the explorer's bloodline traces back to Pedro Álvarez de Sotomayor, a powerful 15th-century Galician lord better known as Pedro Madruga. Researchers say two descendants who, on paper, shouldn't be related shared DNA tied to a missing common ancestor; running 16 generations of genealogies through computational models repeatedly led them to Madruga, EuroNews reports. The study has not yet been peer reviewed.

The work, which relies on more than 10,000 genetic markers and a "virtual knock-out" of candidates from the family tree, offers what the authors call the first genomic evidence consistent with a northern Spanish noble origin. But it stops short of proving Columbus was Madruga or his son—and it doesn't use Columbus' own DNA. The Genoese narrative, backed by Columbus' 1498 will, remains the dominant view, while a separate team has floated a Sephardic Mediterranean origin. Experts say the case won't move beyond intriguing clue without open raw data, independent replication, and broader historical DNA comparisons—meaning the mystery of who Columbus really was is unresolved.
