About us
This project is for anybody who carries the Y-DNA SNP called L554.
L554 is a SNP at position 13532171 on the Y-chromosome. The ancestral allele at this position is A, whereas the L554 allele is G.
L554 was discovered in March 2011 during Y-DNA analysis for a person whose paternal ancestry is from southern England.
L554 is downstream of L21 as well as Z253, so everybody who is L554+ is also L21+ as well as Z253+. Hence R-L554 is within the R-Z253 subclade, which in turn is in the R-L21 subclade of Haplogroup R1b.
If you have tested positive for L554 then please join this project. You should also join the R-L21 Project as well as the R-Z253 Project.
Shown below is the L554 "Time Tree" as of September 2025. The root of the tree is estimated to be about 3500 years old. The tree has two main branches, marked by the SNPs named BY14481 and BY65903, with estimated ages of about 2200 amd 1800 years respectively. Noteworthy surnames within the BY14481 branch are Pike and Humphrey. Within the BY65903 branch, the surname Wilcox is most prominent.
If you suspect that you have the L554 SNP in your Y-DNA, then feel free to join the project. The best way to confirm your placement within the L554 tree is to take the "BigY" DNA test.
