Often people ask about what SNP's they should look at testing, given their particular STR values. In addition, people sometimes ask what can be said about their ancestral geographic origin based again on their STR values. One can in fact answer those types of questions in an objective sense. The methodology I used is quite simple. First, I collected as much STR haplotype data as I could (I got over eight thousand I1 and I2 samples from various FTDNA Projects and from the Ysearch database). Next, I organised that large STR dataset into "hierarchical clusters" using a standard mathematical technique. Finally, I counted up the number of SNP alleles (either positive or negative) that occurred within each cluster, now called an STR "Branch", and I displayed the results; and I also plotted maps of the frequency distribution of the most-distant-known-ancestor of each STR Branch member across all regions of Europe. The results are very informative. The answer to many questions just depend on knowing your STR "Branch Code". In the system I use, the Branch Code is essentially just a way of labelling the STR branches in the computed hierarchical tree, and it is very similar to the "Henry System" used in genealogy for numbering the descendants of an ancestor. To determine your very own STR Branch Code in the system I use, see: http://www.goggo.com/cgi-bin/branchFind.cgi Enter you FTDNA Kit Number or Ysearch ID, and (hopefully) it will return your STR Branch Code. (Only works for y-haplogroups I1 and I2, and 67 or more STR markers at present.) Follow the links to see what your STR Branch Code can tell you. Terry

Terry: Thank you for your work on the clusters or STR branches. It is interesting to see the haplogroups from another view point. By the way, your maps confirm (at least for me) certain suspicions about my cluster.

Terry, Thank you for share your work. Let me make you some questions about the branch I2.0110*. These branch correspon to the I2ab2 haplogroup and acording to the studies of Hans de Beule, the present day distribution is limited to the Upper Rhine and the British Isles. Also in the I2ab2 FDNA project, the most of the samples are British. However in your I2.0110* map with 63 samples, the major figures correspon to France and Switzerland. Therefore my questions are: - How many French and Swiss samples have you used? - Which are your sources? - And if the sources are public, Have you overweighted them or in other words, Have you underweighted the British samples because many of them are the same family? Thanks in advance.

Daniel, The data sources I used, for the STR 67-markers, are from various public FTDNA Projects (mainly the I1 Project), plus data from Ysearch (making sure not to double count the same data). The maps are the *frequency* of occurrence of the particular branch within the given country/region. Here the frequency is the number of people in the branch, divided by the number of people that have been tested in the region. That weighting hopefully reduces the bias of popular DNA testing regions like England, compared to some less popular testing regions. For your I2.0110* Branch, that frequency comes out highest in France and Switzerland. Numerically, there are a large number of I2.0110* people with a reported origin from England, but that large number should be scaled down by the correspondingly large number of people from England that have taken the STR 67-marker test. After that is accounted for, places like France and Switzerland come out the dominant (highest frequency) place. But England, and even Norway, still have a significant frequency of I2.0110*. (In contrast, the I2.00* branch for example, has a very low frequency in England, and a high frequency in Eastern Europe.)

Some improvements, and changes to come: 1) Case sensitivity fixed. 2) Thousands more Ysearch ID's will be handled (sometime next week), including the missing I2 Ysearch ID's. 3) Reverse lookup will come sometime next week as well, and you will get links to your closest Branch Code matches.

Hi Terry First - thank you very much for this. I find it very useful. Second - I think that both you and FTDNA have forgotten the new SNP L813. It seems to be in the shade of all the new SNPs. Being L813+ I would like to draw your attention to the 5 derived and 8 ancestral L813 that has been found so far. The derived are all from the BBA cluster.
