2022, Jannuary 25th

Major experimental SNPs identified concerning various lines (FTT41, FTT42, FTT43, FTT48), especially Lorn/Appin ancestries.

These SNPs are not based on Human Genome 38 references but based on CP086569.1 references built by T2T consortium.

2019, February 15th

A major subclade is identified (S781a). its concerns all cousins FGC74572+ (Identified by co-admin Jeremy Stewart) , R-BY11989+ and with Y-STR off modal value DYD493=9.



2016, October 21th

FTDNA Introduced SNP BY11989 as a new Terminal SNP that subdivide S781 members in two majors lines.
