not exactly but maybe is due to my non proper english.
This suggests that a reasonable proportion of the ancestors of modern-day Albanian speakers are drawn from a relatively small, cohesive population that has persisted for at least the last 1,500 years.
These individuals share similar but slightly higher numbers of common ancestors with nearby populations than do individuals in other parts of Europe (see Figure S3), implying that these Albanian speakers have not been a particularly isolated population so much as a small one.
Thnx for your time
