This project is for people who have tested and been assigned the paternal haplogroup L48/S162 (also known as R1b1a2a1a1a4) or a subgroup of this, and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Defining Mutations

  • L48, also known as S162. Estimation of formation is 4700 years before present (approx 2700 BCE) according to


Likely Germanic tribes.


(to be added)

The path from R to L48

The "R1b1b2a2" notation has proved unstable; this page uses the R-<mutation> notation.

(in revision - will follow the YFull tree)

  • R (formed 31300 YBP) - R-Y482 - R1 - R1b - R1b1 (formed 18400 ybp)

Under R-U106:

  • R-S263

Sister clades to R-L48 under R-S499 include R-U198 and R-L259.

Subclades of R-L48

  • R-S5918
  • R-Y10968
  • R-L47
  • R-Z9
