Can ancestry DNA matches be wrong?
Yes, it is possible for distant DNA matches to be false. It is important to note that a legitimate DNA match can also appear to be false based on not finding genealogical evidence of a connection. DNA segments can get passed down for many, many generations.

What will my AncestryDNA results tell me?
Your AncestryDNA results include information about your geographic origins across 1,000+ regions and identifies potential relatives through DNA matching to others who have taken the AncestryDNA test.
Where does the rest of my ancestry come from?
The rest of my ancestry, it suggested, is as follows: 2 percent traces back to the Iberian Peninsula (that’s Spain and Portugal ); 1 percent traces back to the “European South”; 1 percent traces back to the Middle East; and the rest comes from elsewhere. The second sample produced similar — though, interestingly, not identical — results.
Where did my DNA come from?
The rest of the DNA, according to Ancestry, may have traced back to the Middle East and European South or other regions. But each of those sources accounted for, at most, less than 1 percent of my DNA, according to the site.
