Azores DNA

[Leonard Silva]

I did my DNA through Ancestry and was surprised to see how small the percentage of Iberian heritage was there.  I discussed this with a genealogist at my local library and she told me that for hundreds of years, the Azores were a stopping point for all manner of ships from around he world and that Azorian DNA is much more diverse than one might expect.
Any comments from those of you who have studied this?

Leonard,

If you tested only for the ethnicity estimates, you're really not going to be wowed by any company.

Your sample is run against a population sample at each company and they decide how well you fit. At Family Tree DNA (FTDNA) the sample size was 25. Just 25 to compare Azoreans, Madeirans, Portuguese, Brasilians, etc. No company has a great Portuguese population sample. So you can keep on testing your ethnicity and you will continue to get various estimates.

I think Judy Russell, The Legal Genealogist, says it best: https://goo.gl/ehzUxy

If you want to see how you stack up against the 25 people at FTDNA, you can transfer and pay $19 to see your ethnicity estimates there. You won't be wowed though. But you'll get some nice tools to utilize for your genealogy and you'll be fishing for cousins in another pond. But if you only want the ethnicity estimates, I won't bother.

And if you want a real in depth article, search Roberta Estes' blog: https://dna-explained.com/  She is quite scientific.

Leonard,

Don't stress. 

My dad was born in the Azores, as well as generations of ancestors before him. FTDNA gives him 0% Iberia. And we are OK with it. Also because FTDNA says that «The myOrigins results are your personal genetic ancestry that reflects the last 100 to 2,000 years (about four to 80 generations). They may also reflect one population that mixed with another in ancient times and became fixed in one of your populations.» (source) So my first thought after reading this is "OK, these results can go beyond paper trail, and and Cheri said, are estimated in a small population sample.

These percentages won't give you 100% trusted information, since they are estimates, and can even change on the next FTDNA update. Think of it more like a curiosity :)

Look, Roberta Estes wrote on ethnicity estimates again today, with lots of links to other more in depth articles: https://goo.gl/7n9jBq

I did my DNA with Ancestry and Family Tree. I think Ancestry has a larger data base of information than Family Tree. I could be wrong but the breakdown of my ethnic profile seem more precise with Ancestry. 

However, my Iberian average was higher with Family Tree than Ancestry.

In regards to ethnicity it is diverse in the populations of Spain and Portugal not just the Azores. Before Portugal was a country many ethnic groups went throughout Iberia.

 In regards to the Azores I have read in a history document that many people from Holland settled, especially on three of the islands, in the Azores. In that document it said there were so many that the islands were called the islands of Flanders. 

I do have that document but will post the title of the document later.It was written by a Portuguese man who taught at a California University and the document is especially about the Azorean population of California. 

 

One of my cousins got tested and her DNA was low for Iberian ethnicity but I was much higher. My cousin's  great grandmother is my aunt and we are definitely Portuguese culturally I told her even if you did not have a high percentage. All it means is that you inherited more of the other ethnic groups are ancestors are part of in the long history of Portugal and the Azores. That particular cousin's sister inherited more of the Iberian ethnicity than she did.

Yes, Ancestry bought out several companies and offered free DNA tests in the beginning. That's how they got so big so fast.

Most people feel FTDNA missed the mark with their latest version of ethnicity estimates. However, because they did that survey a few years ago (with the last version) and had 25 Portuguese samples, their Iberian estimate may very well be better. However, if you are testing just for the ethnicity estimates and not genealogy, it's going to be all over the place and you'll need to find some time to dig into Roberta Estes's articles. She explains in great detail what is going on.

Yes, Azoreans come from the Ibeiran peninsula. That is why they will never be able to split Spain and Portugal and it will remain Iberian. That's a political boundary and due to history and the various peoples, yes, it will most likely remain Iberian. I'm sure Roberta has articles about why some areas will never be split.

I have no idea what document you read calling the Azores the Islands of Flanders, but the Flemish did settle there too. Depending on how much Flemish people inherited (and how it gets read by the computer) some of these people show up as Central Europe on their ethnicity estimates.

I believe the man you think taught at California State University at Stanislaus is Bob Santos. No, he wasn't a professor. He was the librarian/archivist and he did NOT write on DNA.

Yes, you and your cousin and sibling will inherit different amounts of DNA. I believe I have posted the link to Roberta Estes' articles. Here it is again in case you missed it:  https://goo.gl/NBBpXv

Happy reading! Cheri

I am brazilian and I descend from Azores from both maternal and paternal lines. My ancestors came from Azores to south Brazil from around 1750 to 1770. I took my dna test with My heritage and they estimated I was 20% scandinavian and 10% northern european, 30% Iberian, 15% Sephardic Jewish, 10% ameridian and the rest is Italian. I uploaded my dna, my mother's and my brother's to FTDNA, Dna.Land, Mylivingdna and Gedmatch. FTDA said I was 48% northern european and Mylivingdna said I was 26% english showing details where in Great Britain and Ireland the particular dna was found. When I started to screen my dna matches in all these sites I found relatively high matches with hundreds of people from all northern countries in Europe (Great Britain and Ireland, Netherland, Denmark, Iceland, Sweden, Norway, Finland) and also with Eastern European countries (Poland, Ukraine and Russia), higher than the matches with people from Portugal and Spain. Besides, I developed a disease in my hands (Dupuytren contracture) that is related to northern Europe. I uploaded my dna to MyTrueAncestry and they pointed to me matches with ancient remains in Great Britain and Sweden,  what directly links with people from these places. I do not know how people were like in Azores in 1750's or if it is related particularly with my family line from there, but I think there is a point in this, not because of the companies estimates but because of the dna matches.
