Ancient Bulgarian T2G2 DNA

Authors had sequenced the DNA from human tooth found in a Thracian tumulus (burial mound) near the village of Stambolovo, Bulgaria. Two small tumuli dating to the Early Iron Age (850-700 BC) were excavated in 2008. A canine tooth from an inhumation burial of a child (c.12 years old) inside a dolium was used for DNA analysis. I converted the raw data of T2G2 sample into formats familiar to genetic genealogists. I also filtered with SNPs tested by DNA testing companies like FTDNA, 23andMe and Ancestry in order to upload to GEDMatch but found this ancient DNA has less SNPs that are common with them. Hence, I did not upload this to GEDMatch. However, complete SNPs are available for download.
