Gombás Y-DNA

In August 2011, I had yDNA testing done through FamilyTreeDNA, a company known for specializing in the study of autosomal DNA, yDNA and mtDNA. The test most beneficial to understanding more about our Gombás ancestors would be the yDNA test. The Y-chromosome is inherited from father to son, and so on, and can remain unchanged without mutations for generations. It is only inherited by men and all of us male Gombash cousins should have the exact same yDNA profile. 

According to our yDNA, our direct paternal line Gombás ancestors show the highest connection to haplogroup I-Y3548, a subclade of haplogroup I-L621 (I > I2 > I2a > I2a1 > I2a1b > I-L621 > I-Y3110 > I-Y3111 > I-S17250 > I-Y3548). Haplogroup I is one of the few remaining indigenous-European haplogroups to survive to present-day. There is a 95% probability that the man who first carried the I-Y3548 mutation was born sometime between 600 BCE and 70 CE. Research points the I-Y3548 mutation as likely having formed while ancestors of this lineage were located in the region between the Vistula and Dnieper rivers (Eastern Poland, Belarus and Western Ukraine). It is theorized that these people may have belonged to the Cucuteni-Trypillian culture, however, we lack genetic evidence. 

Between ~250-550 CE, following the end of Roman control, large-scale migrations of individuals from Central/Northern Europe and the Steppe arrived in the Carpathian Basin (Hungary, Romania, Slovakia, etc.) and the Balkans (Croatia, Bosnia and Herzegovina, Serbia, etc.). Current archaeological and genetic research shows that nearly 50% of men from Bosnia & Herzegovina and Southern Croatia belong to haplogroup I-L621. This suggests a clear "founder effect," potentially reflecting our specific haplogroup arriving in the Balkans may have belonged to the elite of their communities. Furthermore, genetic analysis is rather clear that this haplogroup is almost entirely absent in this region of the Balkans during the Roman period.
