Picó Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Picó to a specific Y-DNA paternal-line haplogroup.
J1-M267
Clade J1
Also spelled: Pico
Picó is one of the traditional "15 Chueta surnames" borne by descendants of Mallorca's forcibly converted Jewish community (conversions 1391-1435, later persecuted by the Inquisition through the 1691 Autos de Fe). Sampled bearers overwhelmingly shared one J1-M267 founder lineage (low haplogroup diversity), consistent with a Middle Eastern/Sephardic paternal origin.

How to read this. A surname match means some people with that surname, in a specific study or family record, were found to share a haplogroup, most likely due to a shared patrilineal ancestor generations back. It is not proof that you personally carry that haplogroup: surnames change through adoption, remarriage, non-paternity events, and independent origin of the same name in different families. For your own confirmed haplogroup, test your DNA with our HaploAI Y-DNA/mtDNA predictor.
