About Debra Katz
Debra Katz has been a Jewish genealogist for over 30 years and has been supplementing her research with genetic analyses since 2001. Debra’s professional work as a communications manager supplemented her research skills; her professional work as an early childhood educator in a Jewish school environment deepened her appreciation of Jewish heritage and traditions. Debra’s father’s Y-chromosome DNA analysis, and all that the results implied, got her going on the 25 year project to uncover the long-term ancestry of his paternal lineage.
