The useful data will be in the frequency, not the absolute counts.

If 100 people from the Isles test L21 and 5 people from France test
it, and 70% of both groups are positive, only by employing the most
twisted of logical leaps would you deduce that L21+ is more common in
the Isles than in France.

Even more useful for answering questions of origin will be estimates
of haplotype diversity, but we are a long way from having enough data
to make those estimates with adequate precision I think.
