J1-M267
Clade J1
High confidence 📍 Mallorca, Balearic Islands, Spain (Chueta crypto-Jewish community)
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.

Carry the Picó name? Find out if you share this paternal line FamilyTreeDNA lineage tests

Surnames follow the paternal line, and so does the Y chromosome. A FamilyTreeDNA Y-DNA test compares you with other men who carry your surname, inside its free surname projects, and tells you whether you descend from the same ancestor.

Y-DNA tests follow the direct father-to-son line, so they are for men. Women can ask their father, a brother or a paternal uncle to test.
