Thank you .
There are those who claim that there isn't much difference between the L21's and S28's:http://listsearches.rootsweb.com/th/read/GENEALOGY-DNA/2009-07/1247409123
I really think its time to open our eyes, look at the continental distributions of the main western European R1b clades and stop all this L21=isles, S21=Germanic and S28=Alpine Celtic labelling. It just does not appear to stand up to scrutiny if you look at the FTDNA projects maps with an open mind.
According to Genebase L21 and S28 emerged at the same time about 3500 -4000
As an Irish Type III, my closest matches are with differnet subclades : R1b1b2a1b5 vs R1b1b2a1a2f. (11 on 76 markers, or 8 on 58 etc.)
Please find where I have done any of the things you are accusing me of.
U152 and L21 are not the same thing. They are related in that they are both P312+, but, beyond that, they are separate subclades descended from separate P312+ progenitors.
A U152+ man with the modern surname Bourbon might or might no be related to the old royal Bourbon family. But the fact that an L21+ man is a genetic distance of 12 from him at 67 markers does not make that L21+ man a Bourbon . . . not even close. The two men aren't even related within genealogical time or even within the last 3,000-4,000 years.
