Pogroms, the Holocaust, name changes at immigration, pre-revolutionary metrical books in Hebrew and Yiddish. Jewish genealogy is one of the most demanding fields — and one of the most methodologically developed.
In the 1990s, American comedian and director Billy Crystal participated in a genealogical project and discovered that his ancestors came from a small shtetl in what is now Ukraine. Almost no direct documents had survived — the shtetl was entirely destroyed during the Holocaust. But using DNA testing, records of immigrant organisations in the US, ship manifests and Yad Vashem databases, researchers were able to reconstruct several generations of his family. This case illustrates both the possibilities and the difficulties of Jewish genealogy. The documentary base exists and it is rich. But the path to it requires knowledge of specific sources, specific databases and an understanding of how record-keeping worked in Jewish communities — fundamentally different from Christian parish practice.
Before compulsory civil registration was introduced (in the Russian Empire from the early nineteenth century, in Austria-Hungary and Prussia somewhat earlier), Jews maintained their own communal records. The main communal self-governance body — the kahal — registered births, marriages, divorces and deaths in metrical books in Hebrew or Yiddish. In parallel, the state required duplication in the official language (Russian, Polish, German). This means: for the same event, several documents may exist in different archives.
The Pale of Settlement — the geographical zone within which Jews were permitted to live in the Russian Empire — encompassed the western provinces: parts of modern Russia, Poland, Ukraine, Belarus, Moldova and the Baltic states. The overwhelming majority of Eastern European Jews descend from there. Ashkenazi naming tradition created recurring names in each generation — children were named after deceased relatives. Combined with a relatively small set of common surnames (Cohen, Levy, Rosenberg, Katz), this creates serious identification difficulties. The full context is always necessary — place, date, parents' and spouses' names.
Surnames. Many Jews received surnames compulsorily — in the late eighteenth and early nineteenth centuries, when states (Austria from 1787, Russia from 1804) required Jews to adopt permanent family names. At immigration, surnames were often altered: transliterated phonetically, simplified or entirely changed to phonetically similar English or German equivalents. 'Schwartz' might become 'Black'; 'Katz' might become 'Katz' or 'Cott'.
Yad Vashem — the National Institute of Holocaust Victims' Remembrance in Jerusalem. The Yad Vashem database contains more than six million records of Holocaust victims, including pages of testimony (survivor accounts of deceased relatives), community memorial books (Yad Vashem preserved thousands of memorial books published by Jewish emigrants about their destroyed communities) and archival documents. This is the first port of call for anyone whose ancestors come from Eastern Europe.
JRI-Poland (Jewish Records Indexing — Poland) — a non-commercial project indexing Jewish metrical records from Poland, Ukraine, Belarus and Lithuania. Contains approximately four million records. Free search. Gesher Galicia — a specialised project for Galicia (modern western Ukraine and south-eastern Poland, formerly part of Austria-Hungary). Contains censuses, land registers and metrical books. YIVO Institute for Jewish Research in New York — the world's largest repository of documents related to the history of Eastern European Jews. Includes community organisation records, periodicals, photographs and memoirs.
Ellis Island and other immigration databases. Most Jews who emigrated from Eastern Europe to the United States in the 1880s–1920s passed through Ellis Island. Ship manifests of that period contain the place of origin, names of immediate relatives in both the country of departure and the country of destination, occupation and physical description. The database is digitised and available on the Ellis Island Foundation website. FamilySearch: the LDS Church microfilmed synagogue metrical books over several decades, many now available free online.
Ashkenazi Jews are one of the most genetically studied populations in the world. This is related to the fact that modern Ashkenazim descend from a relatively small founding population (founder effect) and lived in relative isolation for a long time. As a result, their DNA carries characteristic markers that are well-identified in commercial tests. For Jewish genealogy, DNA testing provides several valuable tools: ethnic identification (the 'Ashkenazi' component is easily identified and well separated from other Eastern European populations), relative finding (DNA matching databases for Ashkenazim are relatively well populated), and the possibility of locating 'disappeared' family branches. An important caveat: the high degree of genetic similarity within the Ashkenazi population means many people see hundreds of 'matches' at the fourth or fifth degree that actually reflect shared population ancestry, not a specific family connection. Results require careful interpretation.
One unique source for Jewish genealogy is the yizkor-bikher — memorial books published by communities of Jewish emigrants in memory of destroyed shtetls. Written by survivors — those who had left before the Holocaust — they contain memories of community life, lists of victims, photographs and family histories. Most are written in Yiddish or Hebrew. YIVO has digitised hundreds of such books. The Yizkor Book Project at the New York Public Library translates them into English. If the family's town of origin is known, there is a good chance of finding relatives' names there.
Jewish genealogy is a field where documentary destruction meets methodological richness. Yes, the Holocaust destroyed millions of people and millions of documents. But what survived has been systematised, digitised and made accessible as never before. Survivors and their descendants across the world spent decades building databases, publishing memorial books, collecting documents. Today a researcher with an internet connection and a few known names and places can reach back into their family's past to a depth that a generation ago seemed unattainable.
