The message arrives in a family group chat. A distant cousin has found something. A manifest. A name. An address on Orchard Street. And suddenly, New York is not just a city on the map. It is where your family began.
Millions of people around the world share this story. They descend from the great waves of immigration that swept through New York between 1880 and 1924. Irish families fleeing famine. Jewish families escaping persecution. Italian contadini leaving behind nothing but hope. Polish, Greek, Puerto Rican, Chinese — all of them passed through this city. Many stayed.
If your family came through New York, the records exist. This guide will show you exactly where to look.

Start With What You Know
Before you open a single database, write down everything your family already knows. Names. Dates. Places. Even half-remembered stories count.
Ask the oldest living relatives first. They may recall the name of the street, the port of departure, or the village in the old country. Even a fragment — “Grandma always said we came from somewhere near Naples” — can narrow your search enormously.
Write it all down. This is your foundation.
Ellis Island: The First Stop for 12 Million People
Between 1892 and 1954, more than 12 million immigrants entered the United States through Ellis Island. Most arrived from Europe. If your ancestors came during that period, they almost certainly passed through its Great Hall.
The Ellis Island Foundation maintains a free searchable database at libertyellisfoundation.org. You can search by name, nationality, and approximate year of arrival.
The records include the original ship manifests. These were completed by steamship company officials before departure. Each manifest lists the passenger’s full name, age, last place of residence, and destination address in America. Each manifest also shows who they were travelling to meet. That final detail — the contact person in America — often leads directly to the first tenement address your family ever called home.
Ancestry.com also holds a large collection of Ellis Island records, alongside census data, draft cards, and naturalisation papers. A subscription is worth considering for serious research.
One important note: names were not always changed at Ellis Island. This is a popular myth. Immigration officers copied names from the ship manifest, which had already been completed in Europe. If your family name changed, it often happened later — at a government office, or simply by choice.
New York City Vital Records
Once your ancestors arrived, they left a paper trail through the city’s official records.
The New York City Department of Records and Information Services holds birth, marriage, and death certificates. Records from 1866 onwards are held at 31 Chambers Street in Manhattan.
You can search the index online at the NYC Municipal Archives website. The actual certificates require an in-person visit or a formal records request.
These records can be deeply moving. A birth certificate from 1902 might list a tenement address, an occupation, and the names of grandparents who never made it to America.
The New York State Archives
For records going back before 1866, the New York State Archives in Albany holds an extraordinary collection. These include early census records, naturalisation papers, and military service records.
The state archives are accessible online via FamilySearch.org, which is entirely free. The Church of Jesus Christ of Latter-day Saints has digitised a vast range of historical records. Their library is one of the best free genealogy resources in the world.

Finding the Tenement Address
This is often the most thrilling discovery in NYC ancestry research: the tenement address.
Once you have a name and approximate year of arrival, the census records are your next step. The US Federal Census was taken every ten years. The 1900, 1910, 1920, and 1930 censuses are all fully available on FamilySearch.org for free.
Each census page lists every resident of every household at a specific address. Finding your great-great-grandfather listed at 147 Orchard Street in the 1910 census is one of those moments that stops your breath.
The Tenement Museum in Manhattan at 108 Orchard Street holds detailed records of tenement residents. They can sometimes help visitors trace ancestors who lived in the Lower East Side. Their research library is a remarkable resource.
The Jewish community of the Lower East Side left particularly rich records. Many families can now find the exact apartment, not just the building.
The YIVO Institute: Essential for Jewish Heritage
If your ancestors were Eastern European Jews, the YIVO Institute for Jewish Research is essential. Based in New York, it holds the largest collection of materials on Eastern European Jewish history outside of Israel.
Their online catalogue is at yivo.org. Staff researchers can assist with specific queries. The institute holds records in Yiddish, Polish, Russian, and German — languages that often blocked earlier generations from accessing their own history.
New York Public Library Genealogy Resources
The New York Public Library’s Milstein Division, located at the main branch on Fifth Avenue, is one of the finest genealogy research centres in the world. It is free and open to all.
The library holds city directories from the 1780s onwards, immigrant newspaper archives in dozens of languages, naturalisation court records, funeral home records, and synagogue and church membership rolls. It also holds extraordinary maps showing how neighbourhoods changed decade by decade.
The Milstein Division’s staff are highly experienced in immigrant genealogy. It is worth booking a research appointment before you visit.
Immigrant Newspaper Archives
This is a resource many people overlook. Immigrant communities in New York maintained their own newspapers, often for decades.
The Irish-American newspaper ran from 1849. Der Forverts — the Jewish Daily Forward — published for nearly 130 years. Il Progresso served the Italian community from 1880.
These papers published lists of passengers newly arrived from Europe, birth, marriage, and death notices, and letters from readers looking for lost relatives. They even published community news from specific villages and towns in the old country.
The New York Public Library holds many of these archives. Chronicling America, maintained by the Library of Congress at chroniclingamerica.loc.gov, offers free access to digitised historical newspapers.
DNA Testing and NYC Heritage
Modern DNA testing can add a powerful layer to your research. Services such as AncestryDNA and 23andMe can identify ethnic origins and connect you with distant cousins who are researching the same family lines.
Many users find that DNA matches lead them directly to the village in Italy, the shtetl in Poland, or the county in Ireland that their ancestors left behind.
DNA alone will not give you names and addresses. But combined with documentary research, it can fill gaps that records cannot reach.
Planning Your Heritage Visit to New York
Once you have found your roots, New York offers something extraordinary: you can walk the streets your ancestors walked.
The Five Points neighbourhood — the Irish heartland of old New York — still has traces of its past visible in the streets of Lower Manhattan. Harlem preserves the enduring legacy of the Great Migration. Astoria in Queens remains deeply and beautifully Greek. Greenpoint in Brooklyn still feels, in places, like the Poland that immigrants carried with them across the Atlantic.
The Tenement Museum on Orchard Street offers guided tours of restored apartments where immigrant families actually lived. It is one of the most affecting heritage experiences in the whole city.
The Museum of Jewish Heritage in Battery Park City holds a remarkable collection on Eastern European Jewish life before and after immigration. The New York Irish Center in Long Island City offers genealogy workshops and a warm connection to the immigrant community.
Your ancestors came to this city with nothing but hope. The records they left behind are waiting for you.
