About us
The discovery of the YSC0000076 SNP in 2013 has defined our deep paternal ancestors. The test is available through Geno 2.0 and as an individual SNP test at Family Tree DNA. YSC0000076 is estimated to be about 3,200 years old and probably originated in northern Iraq or western Iran. Many Brosgol project members have been tested and are positive (derived) for this SNP, which confirms that most (but not all) of the matches based on STR markers have a common paternal ancestor in the last 3,200 years. There are several sub-clusters in the project whose age is more recent than 3,200 years. One of the sub-clusters is defined by the F450 SNP mutation. This paternal line branched off from the larger line about 600 years ago in Spain. It is a Sephardic Jewish line, many of whose members were dispersed after the Inquisition and expulsion of Jews from Spain. Some descendants on this paternal line eventually migrated to Eastern Europe and were absorbed into the Ashkenazi population, while others migrated to the Americas.
Maria Jose Surribas has translated archival records from the town of Cervera in Catalonia, Spain as a project supported by the International Institute for Jewish Genealogy and the Paul Jacobi Center at the Jewish National and University Library, Jerusalem. This has relevance for our Brozgol ancestry since Cervera was a major Medieval Jewish community and a crossroad on the routes leading from France, Girona and Barcelona to the rest of Spain. Here's a link to the website of the Cervera project:

The Genetic Legacy of Religious Diversity and Intolerance: Paternal Lineages of Christians, Jews and Muslims in the Iberian Peninsula was published in the American Journal of Human Genetics, Vol. 83, Dec. 2008. Three of the study subjects are close matches with the Brosgol modal haplotype. Each of these matches is from a different region in Spain: one from Galicia, one from western Andalusia and one from eastern Andalusia. Since only 15 of the 19 markers tested in the study are the same markers that FTDNA tests, there is not enough resolution to get accurate estimates of the TMRCA (time to most recent common ancestor).
Family Tree DNA previewed several exciting innovations at the October 2007 conference in Houston that will become available to project members during the next few months. Bennett Greenspan, CEO of Family Tree DNA, introduced MyMaps, which has great potential for tracing ancestral migration routes out of Spain and Portugal. The MyMaps tool is an innovative genetic mapping system that enables individuals to identify their possible specific geographical origins. MyMaps will display a pushpin on the latitude and longitude of the most distant known ancestor of each of your matches, color-coded by genetic distance. Please make sure you enter the geographic coordinates of your most distant known ancestor's village of origin on the user preference page of your FTDNA personal website.
Dr. Michael Hammer, Geneticist and Director of the Genomic Analysis
and Technology Core facility at the University of Arizona and Family
Tree DNA's Chief Scientist, previewed highlights from his
soon-to-be-published paper on the new phylogenetic tree named the YCC
(Y Chromosome Consortium), a theoretical construct positing how
evolution took place on the Y chromosome. The new tree-branch names will be appearing on your results page and on the project webpage.
"A Walk thru the Y Chromosome" is the significant third in the trio
of Family Tree DNA innovations introduced at the two-day conference.
Thomas Krahn, Director of Family Tree DNA's Genomics Research Center,
made the presentation, detailing a test to sequence vast sections of
the Y chromosome. Those interested in finding family connections can
order a fragment of their own DNA and check for an apparent match with
others who have had the test. This has the potential of being enormously useful in identifying a particular family marker.
