Nagama has a DNA code that is not found among Ashkenazim Jews. Still she is married to a man who has 18 Ashkenazim matches, three of them Levites.

This DNA match is supported by the discovery of the Levite biblical familiy of “Bukkiah”, also a large clan within the Banjara community. 10 per cent of male Ashkenazim Jews are of the haplogroup R1a-M198. A distant forefather of Nagama’s husband seems to be one of them. She her self is of the mt-haplogroup U2c. This female haplo-group is not found among Ashkenazim Jews. This married couple fits perfectly into a 2.500 year old drama. In 538 B.C the High Priest Ezra put pressure on those Levites who had married outside of the tribes of Israel. They were forced to send their wives and children away, or the husband had to leave the commonwealth of Israel, just after their return from exile in Babylon. There was opposition to this demand for separation. And some men from the tribe of Levi possibly left with their spouses.
Ezra 9-10
9:2 They have taken some of their daughters as wives for themselves and their sons, and have mingled the holy race with the peoples around them. (…) 10: 3 Now let us make a covenant before our God to send away all these women and their children, in accordance with the counsel of my lord and of those who fear the commands of our God. (…) 10:15 Only Jonathan son of Asahel and Jahzeiah son of Tikvah, supported by Meshullam and Shabbethai the Levite, opposed this.
