Chenini-Douiret Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Chenini-Douiret to a specific Y-DNA paternal-line haplogroup.
E-M81
Clade E1b1b
Also spelled: Chenini, Douiret
E-M81 was found fixed (100%) in this Berber isolate, one of only two Tunisian samples in the study showing complete fixation; unusually high haplotype diversity indicates long-standing isolation rather than a recent bottleneck.

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.
