The results below show the ancestral origin of those I match or nearly match in the RAO. The ancestral origin information is provided by each testee, and is only as accurate as the testee's knowledge. Testees are instructed to answer "Unknown Origin" when their ancestor's origin is uncertain or not known.

Incorrect origins provided by testees may lead to search results that do not seem logical. for example: Assume your ancestors are from England, but your search results show the ancestral origin of your matches as England, France, AND one match shows an origin of Native American. Does that mean that your ancestors relatives may have lived in England and France? Yes. Does it mean that your ancestor was also a Native American? No. This means that a settler in America had a child with a Native American woman, the child was brought up as a Native American, and that, over time, the family has "forgotten" the European ancestor, and believe their ancestry to be Native American.

Over the span of generations people tend to move, as do borders, so nationality or ethnicticity becomes subjective. for example, testees may enter Germany for ancestral origin, because the land of their ancestors is Germany today, but the land could have been held by Denmark for many centuries.

To see how your ancestral origin is recorded in our database, click on the link above entitled Update Contact Information. You may also update your paternal and maternal ancestral origin on the Update Contact Information page.

Exact matches show people who are the closest to you genetically. The Ancestral origin shows where they have reported to have lived. Since many persons migrated over the past few centuries, you will typically see matches in more than one country.

for information purposes, the Recent Ancestral Origin search also displays results for those who are near matches. A near match is either one step or two steps from your result. An exact match is 12/12 or 25/25. A one step match is 11/12 or 24/25 and the magnitude of the mismatch is 1. A two step match is 10/12 or 23/25 and the magnitude of both mismatches is 1, or it is 11/12 or 24/25 and the magnitude of the mismatch is 2. Near matches show where those who are distantly related to you have migrated over time.
 


For Genealogy usage FTDNA does not evaluate past 4 steps of mutation.  
It is their belief  that on average paper trails don't go back farther, although they have not presicely told me this, they have said it in reoundabout terms.

Modal haplotypes associated with Y-chromosome Haplogroup R.
A few notable STR-based haplotypes have been described for subclades in Haplogroup R.  The most prominent of these is the Atlantic Modal Haplotype that is widespread on both sides of the Atlantic Ocean.  This is due to its association with the R1b subclade, which is by far the most abundant Y-chromosome lineage in Western Europe, where it reaches nearly 100% frequency in some populations in the British Isles and the Iberian Peninsula.  Given the hegemony in Western European nations, it is not surprising to find a high level of R1b and AMH also in the Americas.  A few related R haplotypes, e.g. Irish Modal Haplotype and a modal haplotype for the Basque population are also linked to the West European R1b ancestry.  It has been noted that the IMH is largely absent from neighboring England, but could be found at modest frequencies in Scotland and the U.S.    

Confirmation of haplogroup assignment is always made by SNP testing.  Conversely, haplogroup assignment does not indicate that you will have the modal haplotype, recalling the fact that STRs are rapidly changing markers.  Table 2 provides a list of modal haplotypes associated with Haplogroup R.

Notes: 1 and 4:  Modal types are determined by only 8 markers.  Atlantic and Iberia are a match.

I'm not sure what I have here but FTDNA relates all these names to R1b Western European origin. This lineage is also the haplogroup containing
the Atlantic modal haplotype.

Viesca,  Zaballa,   Zeberio and Zuloeta/Zulueta; 

Basque people belong to this Haplogroup and they were among the earliest settlers of the Iberian Peninsula. 73% of modern day Basque share this origin.
The following markers are common to the people bordering Europe's Atlantic within a couple of steps; DYS19 (DYS394)=14, DYS388=12, DYS390=24,
DYS391=11, DYS392=13 and DYS393=13.

Based on these data I have a distance of 16 from the Atlantic modal Haplotype - kinda leaves me out

I have decided to put my actual data on my web
