Your percentage from any one reference population may reflect either recent or long term genetic ancestry. Determining which it is requires that you evaluate your results in light of what you know of your family history and the history of your ancestors.
Having about one third of your ancestry from a population may indicate that there has been recent admixture in your family. That is, some of your recent ancestors were from that population.
On the other hand, it may indicate that some ancestors migrated from the location of the reference population and lived in their new location for many generations. Thus, the admixture levels are common to all from the town’s population.
