My colleagues and I have already identified the Y-DNA genetic signature of Rabbi Levi Yitzchak of Berdichev's patrilineal lineage, that is largely known by the Derbaremdiker surname. This will be one of many rabbinical lines to appear in our forthcoming book: "Unlocking the Genetic Code of History’s Great Rabbinical Lineages, Dynasties, and Tzaddikim," subtitled: "Discovering Your Lost Heritage through Y-DNA."
