The Expulsion of Jews from Spain, 1492 CE - Internet History Sourcebooks Project
Almost every southern European nation has asserted rumors that he was "really" from their country—Spain, Portugal, other parts of Italy instead of Genoa, etc. He has been described as being six feet tall, having reddish blond hair, freckles and blue or hazel eyes, so... it's possible, but unlikely, as there were Celts all over that region. More will be known when results of the DNA tests begun in 2021 on his exhumed bones and swabs from the many families in the Mediterranean region named Columbus, Colon, or variants, are completed:
International Team to Study Columbus DNA to Determine His Origin
DNA Tests on Christopher Columbus' bones, on his relatives and on Genoese and Catalan claimants
