Clade R1a
Case study confidence 📍 Lotli, Goa / Konkan coast, India
Also spelled: GSB; Gaud Saraswat Brahmin; Shenvi
A rare R1a1 L657 subclade was found in most male members of a specific clan of "founder families" within the Goud Saraswat Brahmin community of Lotli, Goa; the authors argue for a distinct Bolan Pass migration route for this lineage, separate from the canonical Brahmin ingress narrative.

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 Goud Saraswat Brahmin (Lotli lineage) 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.
