Nikaj Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Nikaj to a specific Y-DNA paternal-line haplogroup.
J2b2a1 (J-M241>L283)
Clade J2b
Also spelled: Nikai
6 men of the Nikaj fis were Y-DNA tested and carry the same ancestral J2b-L283 lineage as the Krasniqe clan, but lack the derived mutations found in Krasniqe carriers, placing the clans' divergence before roughly 1500 CE. Smaller sample size than the Krasniqe branch of the same study, hence Medium rather than High confidence.

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.
