R-CTS4528 is a y snp mutation that occurred some 5000 years ago - On average males acquire a new snp mutation every 140 years or so meaning that there are many new branches that exist under CTS4528 being discovered on a regular basis, testing BIGY "Comprehensive Genome" will help with these new discoveries and establish what branch you belong to and with whom.
S14328 - A downstream subclade of SNP's < CTS4528 / DF100 < S1194 < P311 < L11/P310 < L151 < L23 < M269.
We are looking for members who have or may test positive for CTS4528 & downstream subclades and have an interest in related Family History and are willing at least in the future to test further downstream SNP's / subclade’s as they develop to substantiate your most downstream SNP/(up to date), bringing our members y-DNA samples within the scope & timescale of fixed & recent recorded surname history, In turn helping us to discover recent family histories and cultural ethnicities.
