This project is for anyone whose paternal line has tested positive for E-Z36123 (https://www.yfull.com/tree/E-Z36123/) or one of its sub-markers which originated with Yitzhak ha-Sangari, the ancestor of the כהן מדין House of Aba, the Cozlone Kahans of the Josephite & Simeonite "Black Khazars" who settled in the Romanian areas of Satmar (Kazár) and Cuzdrioara (Kazár Fortress) in Crișana (Kazár-Országa) from whence they spread around the globe. The Cozlones were also known as Black Magyars, Black Cumans, Black Ugors, Black Hats and Black Bogdans. The Clan of Aba descends Matrilineally from the Chernivtsi Cozlones' House of Pota (the Hungarian word for the Black Khazar Leaders). This project is only for members of one single Byzantine Jewish lineage from 8th Century Sangarus which inspired adoption of Noahide Judaism among Black-Gazaria's Cozlones and Kavars who followed their Byzantine Jewish teachers to various areas of Greater Romania. It does not deal with Unconverted Turkic "White Khazars" of the Volga Basin at all.
