It does seem that people from Cornwall have a considerable percentage of genes from people originating in the Iberian Peninsula, Zib.
It may be due to the fact that on August 2, 1595 Spanish forces under the command of Carlos de Amesquita landed just off Mousehole and over two days these troops sacked and burned Mousehole, Paul, Newlyn and Penzance. But perhaps it could also be due to the fact that in early history Celts from the Iberian Peninsula settled in Cornwall.

I think the earlier posts in this thread show that the effect of a few soldiers over a short period of time would have done little to the long term make up of the local population. The Mousehole etc sackings and the Armada survivors having that effect on the Cornish would appear to be but a magical story.
The movement of peoples around the globe is becoming more and more clear by the use of DNA... however it is not a simple process to understand. Stephen Oppenheimer is one good example of someone who has produced some excellent books and articles and are well worth a read - particularly for those who want to understand where they fit into the migration of people out of Africa.
My Ancestry.com DNA test shows me to be 35% Iberian peninsula and I have no recorded ancestors from that area... this has been a fascinating read and might do some explaining on why I have this result.
That is a major percentage, Steven! I've recently received my results, and they continue to update. I have matches that make perfect sense, and others that bear a strong suggestion yet are 10 to 11th cousins as far as I can tell. I don't expect the test to be that sensitive but have pretty good records on those lines. Not sure what to think. I understand the limits of the database with which my test is compared.
Zibetha... you may be on to something. I've had the DNA testing done by three companies; Ancestry.com, 23andMe, and FamilyTreeDNA. The three of them could not be more different. Ancestry shows me at 35% Iberian Peninsula, 23andMe shows me at 1.9% Southern European (actually it was over 6% but 4% was Italian) and FamilyTreeDNA shows me at 15% Southern European. The three results are VERY different and makes me wonder which one is closest to reality. Ancestry has me at 7% Great Britain and 16% Ireland...23andMe has me at 43.6% British & Irish, and FamilyTreeDNA has me at 18% British Isles. Oy
Mostly North to South: 20% Scandinavian, 69% Europe West, 8% Iberian peninsula, 2% Ireland, less than 1% Africa. No British.
My Ancestry matches so far link mostly to a great-grandfather who was born in the US whose his father died when he was three years old. His mother remarried and took him and an older sister with her on her new "journey" leaving 5 children behind with her in-laws in Indiana. It took me 15 years to put it all together, so the DNA matches to 4+ branches of that family are astounding to receive-- my research was correct, and this is my one link that goes back to colonial America.
I am not sure how their system churns through its records. I have one match to another American member of the Hocken family and yesterday one to a Trewhela cousin in Australia. I seem to get more "news' on Fridays.

Steve, Ancestry DNA info has maps to show the area of influence of the various ethnic groupings. They each have a concentrated core then a middle area and an outer area. These areas can be quite large and there is considerable overlap. Ireland for example has Ireland as its core but the outer area covers all of the UK. The outer area of the Iberian Peninsula covers Cornwall and Wales. I would assume that the other DNA companies have similar maps. They would need to be looked at to make sense of the different results, until that happens you might be comparing apples with oranges. If you have a large number of Cornish ancestors you might want to work out how each of the companies treat the Celtic factor. That might help make more sense of the results.
As for what is the reality, check out your 32 great great great grandparents and work out which ethnicity grouping they would fit in for each company. Based on what you know of your ancestors you should then be able to determine which, if any, of the results comes out close to reality.
