Extending your haplotype will contribute nothing to the specifics of whether
your ancestors migrated to Britain before or after the Roman Conquest, other
than its contribution to better data on and understanding of the clade as a
whole. There is one exception to that: if you are seen to belong to the
I1a-AS1-H subclade of I1a-AS1 then one can probably say that sub-clade's
founder lived in Scotland or northern England.

It seems the questions we ask grow in specificity as fast or faster than the
data accumulates (it now grows very slowly due to fall off in haplotype
upgrades by folks), so answers to those questions don't grow in clarity.
