About us

The Little Scottish Cluster is a group of R-L21 men who share a common ancestor about 1000 to 1500 years ago. There are a wide variety of surnames in the project. The majority of men in this group (but not all) trace their ancestry to southern Scotland, where the common ancestor is believed to have lived. Thanks to recent NGS (Next Generation Sequencing) technology, we now know that all of the men in the cluster belong to the Y-DNA haplogroup R-S424. This project was once called the Little Scottish Cluster project, but now just goes by R-S424. With the exception of the Reddin men and those closely related to them, the rest of the men in this cluster belong to the downstream haplogroup R-CTS2187/R-S190. You do not need to be deep clade tested to join the project, but your predicted haplogroup should at least start with R1b. Your haplotype should have DYS464a=13 (some exceptions permitted) and DYS590=9 (if tested, no exceptions). It should also have most of the following values: DYS391=10, DYS 458=18, DYS449=30, GATAH4=10, DYS413=22-23. Men in this group should test positive for the SNP S424 or one of its downstream SNPs such as S190. Please see background section for more information.
