Due to the large variation in STR signatures in the CTS4466 branch of Cain, Kane, Keane men, I’m recommending the updated R1b-FGC11134 Panel (including CTS4466) from YSEQ. The reasoning is because there is too much genetic variation to easily say FGC29071 marks the separation of Kane from McCarty and O’Donoghue. Other common surnames like McCarthy, Sullivan, and Donoghue have had multiple origins discovered in Big Y testing. This could be a factor in what we see in the smaller Kane cluster.
YSEQ’s R1b-FGC11134 Panel includes the latest research results from 106 Next Generation Sequencing tests under FGC11134. This has revealed around 60 distinct lineages which may be the source of one or more branches now carrying a variant of the Uí Catháin or Mac Catháin surnames. The currently $69 test at YSEQ will test all the appropriate branches using a two phase approach. Once completed they will report your current known position in the tree. Using that knowledge allows identification of a possible origin story and insight into the mechanisms driving the large drift in STR signatures.
