About us

R-L238 is a branch of R1b under the large R-P312 group

This project aims to explore the subclade. Please join if you are confirmed L238+, or strongly suspected through DYS385=11-13 and DYS439=11 at Y12, perhaps also DYS446=15 at Y67.

Subclades of R-L238

So far little is known of the L238 group, and we need many more testers, especially for BigY. Our updated L238 SNP tree is visible also in the Big Tree service


Main SNPs and Branches under investigation:

L238 -> Z2246 -> Z2248 -> BY2048 -> Most populated branches

  • Z2246 (first known branch after L238)
  • Z2248 (first major branches)
  • BY2048 (before this mutation most of the members have their known origins in the Continental Europe or British Isles. After BY2048 the origins are emphasised in Scandinavia) 
  • BY4663 (British Branch)
  • BY3451 (Swedish Branch)
  • A6292 (Norwegian Branch)
  • BY4675 (3rd Scandinavian Branch)

Y-full tree


As more L238 men do the BigY, we will discover further potential subgroups.
