At the 2014 annual conference of the Federation of Genealogical Societies, Anna Swayne of Ancestry.com presented the session “Utilizing AncestryDNA Matching to Break Through Brick Walls in your Research.” This is the second of three articles about that presentation.
When you get your DNA tested from AncestryDNA, you get two types of results: an ethnicity estimate and a report of matches.
To calculate your ethnicity, AncestryDNA compares your DNA against 26 different global regions and gives you an estimate of your ethnicity. This indicates your ancestors’ locations at about 500 to 1,000 years ago. This is based on population research results as of today. As AncestryDNA improve that research, AncestryDNA reruns your results to get improved results.
The results can look different between you and your siblings. Remember the alphabet block diagram from my last article? You inherit different DNA from your parents than your siblings, so your ethnicity estimates can look very different.
