Just got confirmation of new snp downstream of R-BY17958; that being R-FGC65842. My great nephew, Edward also has this. My paternal birth father(1902-1978) was Edward's paternal great-grandfather. I was born 1958 & Edward was born in the mid 1980s. We already knew the approximate age of R-BY17958 was between 1538-1672, so this snp mutated between 1693-1902. There are 5 equivalent snps showing w/R-FGC65842, so that will probably sort out eventually. 
Best regards, Doug
