Ancestry DNA Ethnicity Results Vs Expected Ethnicity Results

I received my Ancestry DNA results a few days ago.  Some of the ethnicity results were surprising, especially in light of the information I have on my constructed family tree & the countries of origin of my ancestors.  I decided to compare my ancestors’ countries of origin to my Ancestry DNA ethnicity results.  I chose to look at my 3^rd great grandparents for this analysis because this generation was the most recent & ‘purest’ in terms of ethnicity; of my 32 3^rd great grandparents, 31 were of a single ethnicity, e.g. Irish, English, Prussian. Only one ancestor was mixed, the son of a Welsh father & and English mother.

Ethnicity Results - Ancestry DNA Vs Documented Country of Origins

Expected Ethnicity Results based on Constructed Family Tree:

Irish – 19%

European West – 19%

Great Britain (England) – 55%

Great Britain (including Scotland & Wales) – 62%

Ancestry DNA Ethnicity Results:

European – 98%

Ireland – 38%

Scandanavian – 26%

Europe West – 24%

Trace Regions

Europe East – 4%

Great Britain – 2%

The Irish portion of my DNA is easily explained.  However, I was surprised at the percentage, given that about 18% of my 3^rd great grandparents were Irish.  Although I guess approximately 62% of my 3^rd great grandparents on my paternal grandfather’s side were Irish.

European West would cover my Prussian / German heritage.  Almost half of my mother’s ancestry is Prussian, & ¾ of my 3^rd great grandparents on my maternal grandmother’s side are Prussian.

The Scandanavian section of my DNA was surprising, but early Scandanavians migrated to modern-day eastern Germany & Poland (which overlaps with European West).  Vikings also inhabited parts of Ireland in later centuries.

What surprised me even more was that only 2% of my DNA is from Great Britain.  More than 50% of my 3^rd great grandparents were English.  All of my 3^rd GG on my maternal grandfather’s side were English & ¾ of my 3^rd GG on my paternal grandmother’s side were English.

So, what conclusions can I draw from these results?  Overall the majority of the DNA passed on to me by my father was Irish, while at least half of the DNA passed on to me by my mother was western European (Prussian / German).  The next largest chunk of ethnicity is Scandanavian, which really could have originated from either side through Irish / Prussian descendancy.  Very little of their English DNA was passed down to me.

After reading Sharon Muffett’s post about her Ancestry DNA results on her blog gathering dust, & how she has converted these results to Family Tree DNA, my next step is to transfer my results to FTDNA & compare the ethnicity results from Ancestry DNA & Family Tree DNA.

Then, maybe, just maybe, I might be able to convince some relatives to have their DNA tested.
