New study suggests that Christopher Columbus was a descendant of Galician nobles

The genetic analysis of 12 individuals buried in a family tomb containing descendants of Columbus suggests that the famous navigator had a connection to the Galician noble Sotomayor lineage.

A new scientific study has reignited the old debate over the origins of Christopher Columbus, presenting genetic evidence linking the explorer to the Galician nobility of northern Spain.

The findings challenge the widely held view that Columbus was born in Genoa, Italy, and instead point to a possible link to the powerful Sotomayor lineage.

The research, led by scientists at the Complutense University of Madrid and the Citogen Laboratory, was a preprint on bioRxiv and has not yet been subject to peer review. The conclusion is based on DNA analysis of remains found in a family tomb in Gelvesnear Seville, where descendants of Columbus are buried.

When examining the genetic material from 12 individualsresearchers identified an unexpected connection between two figures who, according to historical records, should not share the same ancestry. Using computer genealogy models spanning 16 generations, the team followed this connection until Pedro Álvarez de Sotomayoralso known as Pedro Madruga, a prominent 15th-century Galician nobleman.

To test the hypothesis, the scientists applied a “virtual knock-out” method, removing Pedro Madruga from the reconstructed family tree. The genetic link between the two individuals disappeared, reinforcing the idea that could be a common ancestor. The analysis was carried out using advanced sequencing techniques on thousands of genetic markers, a method rarely applied to such ancient remains.

The theory that Columbus may have had some connection with Pedro Madruga is not new. Historians have long observed intriguing coincidences: Madruga disappeared from records around 1486, the same year that Columbus appeared at the court of the Catholic Monarchs. Linguistic clues in Columbus’s writings and elements of his heraldry have also been interpreted as consistent with Galician-Portuguese origins.

Despite the compelling evidence, researchers warn that discoveries are indirectbased on the DNA of descendants and not Columbus himself. Independent verification and peer review will be required to confirm the results.

For now, the theory of Genoese origin, which is supported by Columbus’ own will, remains dominant among historians. However, advances in genetic analysis are providing new tools for revisiting centuries-old questions.
