Probably not. Our reference panel includes samples from many places around the world, but not from every country or population. Similarly, we have identified hundreds of ancestral journeys, but only for areas where we have enough data.
There are some other reasons an ancestral region might not appear in your results. For places like Europe, where the population is very admixed, it can be difficult to distinguish one population from another through DNA testing. And because of the random nature of DNA inheritance, you may not have inherited DNA markers that we identify with a particular region, even though your ancestors may have lived there.
For ancestral journeys based on Genetic Communities technology, you'll only connect to those you have a strong DNA relationship to. So, the more generations that separate you from the population one of our journeys ties back to, the less likely it is that you’ll connect. It’s also more likely that you’ll connect to a population that both your parents have descended from, for example, than to a population that only one of your grandparents is from.
As we gather more samples and our database grows, we'll be able to add more ancestral regions and journeys.
