Larkin Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Larkin to a specific Y-DNA paternal-line haplogroup.
R1b-M222
Clade R1b (R1b-L21 subclade; "Irish Type III")
Also spelled: O Lorcain, O'Larkin, Larkins
Of 34 Larkin project members with 37-marker results, 94% fell within Haplogroup R1b and 56% within the R1b-M222 cluster. Two R1b-M222 subtypes tied to 18 ancestral parishes along the Shannon River match the traditional descent of the Larkin clan (Muinter Lorcain) from Maine Mor, founder of the Gaelic kingdom of Hy Many (5th century CE); median TMRCA for these two groups was about 1,470 years.

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.
