Jewish Genealogy and DNA

Your DNA says you are related to half of Ashkenazi Jewry. Now what? If everyone appears to be your cousin, how do you find your actual family?

Jewish genealogy is different. Names changed across languages and borders. Patronymics, spelling variations and anglicised surnames can obscure the paper trail. Communities moved through the Pale of Settlement, Western Europe, the Middle East, North Africa, Britain, Australia, South Africa, the United States and beyond. The Holocaust destroyed families, towns and records. And for many Jewish researchers, centuries of endogamy can turn DNA matches into a confusing maze of distant cousins.

Jewish Genealogy and DNA is a practical guide to tracing Jewish roots using historical records, family trees, DNA testing and genetic genealogy. Written for beginners as well as researchers facing difficult brick walls, it explains how to combine traditional genealogy with modern DNA tools so that records and matches work together rather than in isolation.

Inside, you will learn how to:

• Start and organize a Jewish family history project
• Build a documented family tree step by step
• Understand Jewish naming patterns, surname changes and migration history
• Use vital records, cemetery records, synagogue records, immigration records and community sources
• Research families from the Pale of Settlement and other Jewish communities
• Trace relatives through Holocaust and post-war records
• Choose the right DNA tests and understand what each test can and cannot tell you
• Interpret autosomal DNA matches, shared centimorgans, clusters, triangulation and chromosome segments
• Use tools from Ancestry DNA, My Heritage, Family Tree DNA, GED match and DNA Painter
• Recognize the impact of endogamy and avoid common mistakes in Jewish DNA analysis
• Combine documentary evidence and genetic evidence to break through family-history brick walls
• Preserve your research and share it responsibly with future generations

Whether you are opening your first family tree, trying to identify an unknown ancestor, sorting through thousands of DNA matches, or reconstructing a family disrupted by migration and loss, this book gives you a clear path forward.

Your ancestors left traces in both records and DNA. Jewish Genealogy and DNA shows you how to find those traces, interpret them carefully, and turn them into a family story supported by evidence.
