Tusi Lu (陆/魯, claiming descent from Jochi via Toghan) Surname: Y-DNA Haplogroup
Published genetics research or a documented case study links the surname Tusi Lu (陆/魯, claiming descent from Jochi via Toghan) to a specific Y-DNA paternal-line haplogroup.
C2b1a1b1-F1756
Clade C2
Also spelled: Lu, Tore (Kazakh cognate clan)
Y-STR/SNP haplotype of the Lu clan (holders of a hereditary Tusi/chieftain title in Yunnan who claim descent from Genghis Khan's son Jochi via Toghan) clusters with the Kazakh Tore clan, which independently claims Jochid descent; estimated common ancestor ~1000 years ago. A published commentary (Journal of Human Genetics 2021) disputed the genealogical claim as unverifiable/likely a later fabricated pedigree, so treat as a documented but contested case study, not a settled finding.

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.
