DNA Study Links Columbus to Galician Noble Sotomayor

Columbus Was Not Genoese: He Was the Galician Noble Pedro Álvarez de Sotomayor

The theory is not new, but it resurges whenever a mass-market documentary touches on the Admiral's DNA. Proponents of the Galician origin argue that the navigator and the nobleman Cristóbal Pedro Álvarez de Sotomayor, Viscount of Tuy and Count of Caminha, were the same person. The central argument: Pedro Madruga disappears from historical records just as Columbus appears at the Castilian court, and the Catholic Monarchs would have offered him a change of identity, renouncing titles and possessions in favor of his children, or facing punishment for having fought on the losing side of the War of the Castilian Succession.

The Calligraphic Analysis cited in the material points to the same individual. The theory also rests on a detail difficult to explain with other hypotheses: Columbus bequeathed lands located in Porto Santo de Poio, in the Pontevedra estuary, something that fits neither the Genoese nor the Catalan thesis.

The 500 Galicianisms in Columbus’s Writings

Columbus wrote in Castilian with Galician turns of phrase. There is no trace of Italian in his letters, even when addressing his brothers or Genoese bankers from whom he sought financing. His writings contain more than 500 Galicianisms and Atlantic maritime jargon, but no Italianisms or references to the Mediterranean. He also named more than a hundred geographical antiestéticatures with place names exclusive to the Rías Baixas, such as Punta Lanzada or the Miño River.

The character’s education does not fit that of a humble wool merchant either. Columbus handled Latin, geography, and Sacred Scriptures, knowledge that, according to contemporary biographers, he acquired in childhood. Pedro Madruga, a legitimized illegitimate son, was educated to be a cleric before becoming heir to the Sotomayors. The Genoese merchant Cristoforo Colombo, however, left a documentary corpus unrelated to the discovery and showing no sign of such culture.

The Age That Doesn’t Match and Italian Witnesses

Columbus died in 1506, when contemporaries attributed more than 70 years to him. The Genoese merchant Cristoforo Colombo was born in 1451, which would make him 55. Pedro Madruga was born in 1432: he would have been 76. The arithmetic is tight.

An Italian, Toscanelli, considered him Portuguese. The main Hispanic historians of the era—Fernández de Oviedo, Andrés Bernáldez, and Bartolomé de las Casas—denied he was Italian and affirmed he deliberately obscured his origins. The chaplain of the Catholic Monarchs, the Italian Lucio Marineo Sículo, who met him personally, called him Pedro Colón.

Supporters, Relatives, and the Columbus Lawsuit

Columbus’s main patrons were relatives of Pedro Madruga. His vvife, Felipa Moniz de Perestrelo, was noble and cousin to Teresa de Távora, herself a relative of Madruga. A commoner did not marry a noblewoman nor was received at court. Columbus claimed descent from four Admirals of Castile, as was the case with Pedro Madruga.

When the lengthy succession lawsuit occurred after the death of the last male descendant, between 1579 and 1796, no relative of Columbus appeared in Genoa, nor anyone with news of that family, despite diligent searches. The Catholic Monarchs always considered him their subject and never required him to naturalize or swear loyalty, unlike what peine with the Florentine Amerigo Vespucci.

What Does DNA Say About Columbus’s Origin?

DNA tests between descendants of Pedro Madruga and Columbus in Puerto Rico show, according to proponents of the thesis, a 93% match. The study is linked from academic repositories. The technical objection is known: remains attributed to Columbus barely preserve usable genetic material traces, and the documentary study pointing to an Aragonese and Sephardic origin has not been published.

The discussion drifted toward more basic ground: the existence or non-existence of a specifically Jewish genetic marker, comparable to a supposed Buddhist or Muslim DNA. The short answer is that no such thing exists. What exists is a historiographical debate spanning two centuries, pioneered by Celso García de la Riega and later developed by Alfonso Philippot.

With deteriorated DNA and no peer-reviewed publication, the Galician hypothesis will continue to win on documentation what it loses on genetics. If clean sequencing of the remaining bones ever happens, the question will cease to be rhetorical. Until then, each documentary will sell its version, and each archive will keep its own.
