Nice overview of things Ellen. I agree with everything you said until the part below <snipped>. I take exception to one or two points you make since there is no evidence to back up some of the conjecture.
Where do you find evidence that R1a was in Britain in Neolithic times? Although at this point we can't be certain of much, the evidence coming from studies at TCD for Ireland indicate almost zero R1a - particularly in the Western areas. The only R1a is found in the areas known to have been settled by the Vikings. Jim Wilson was the first to state that R1a is "the" Viking marker in Britain. If you are R1a, and your ancestors came from Britain, then it is a slam dunk that they arrived there with the Vikings - although it is possible that some few relate to earlier immigrants such as the Western Sarmatians.
As far as I can see there is no evidence of ancient Britons being anything but R1b and I1c (now I2) as reflected in the work being done at TCD. The few J2, G2 and so on in britain can be best explained as a funcition of the well documented presence of Sarmatian and other Roman mercinaries who are known to have settled in Britain after their military service (many were given land grants there).
If you have even a snipit of evidence that R1a in Britain is anything but a Viking marker I would like to see it - and so would the academic world at large.
