Katzenellenbogen Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Katzenellenbogen to a specific Y-DNA paternal-line haplogroup.
J-L823
Clade J1
Also spelled: Ellenbogen, Kellen
Three pedigreed descendants of Rabbi Meir Katzenellenbogen ("Maharam of Padua," c.1482-1565) matched on 66/67 STR markers under haplogroup J-M267, subclade J-L823. Authors interpret matching patterns among Y-DNA relatives as supporting evidence of possible Sephardic/Iberian ancestral origin before the family's move to Padua and later Poland.

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.
