You can trace a New York City ancestor in about six steps. Start with what your family knows. Then search the passenger lists, the census, the city’s vital records, and the old newspapers. Most of these sources are free. Many are online. This guide shows you where to look and in what order.
Updated October 2026: the old Castle Garden website no longer works, so we now point you to the free passenger-list searches at the Statue of Liberty-Ellis Island Foundation and FamilySearch. We also corrected where New York naturalization records are held and the vital records years, checked on statueofliberty.org, archives.gov and nyc.gov/records.

New York was the front door for millions of families. Ellis Island opened in 1892. From 1892 to 1924 it was America’s largest and most active immigration station, and over 12 million immigrants were processed there (National Park Service). Ships brought newcomers from Ireland, Italy, Poland, Russia, Greece, China and the Caribbean. Many stayed in the city. Many moved on. Either way, your family’s paper trail probably passes through New York.
The city also kept good records. Brooklyn, Queens, Staten Island and parts of the Bronx only joined New York City in 1898. Before that, they kept their own files. That split matters when you search. We will flag it as we go.
Step 1: Start With Your Own Family
Begin at home. Ask the oldest relatives what they remember. Write down names, dates, streets and jobs. Note which church or synagogue the family used. Ask about the old neighborhood.
Look through shoeboxes and albums too. Birth papers, citizenship papers and funeral cards all help. Even a postcard can name a street. A photographer’s stamp on the back can name a block.
Write down the spelling of every name. Spelling changed often. A Kowalczyk became a Kovalchik. A Giovanni became a John. Keep every version. You will need them all.
One myth deserves a quick fix. Ellis Island officers did not change family names. The Statue of Liberty-Ellis Island Foundation explains that arrival records were filled out at the point of departure and that “immigrants were not given new names upon arrival.” Families usually chose a new spelling later, to fit in.
Step 2: Search the Passenger Records, Including the Castle Garden Years
Passenger lists tell you when your ancestor arrived. They also tell you a lot more. Later lists often name the home town. Many name a relative back home. Many name the person the traveler planned to join in America.
Castle Garden, today’s Castle Clinton in Battery Park, was the immigrant landing depot from August 3, 1855 to April 18, 1890 (National Park Service). The old Castle Garden website no longer works. These free searches cover most arrivals in New York, Castle Garden years included:
- The Statue of Liberty–Ellis Island Foundation database. Its Arrival Records Collection covers Ellis Island and New York, plus other U.S. ports, across the 18th, 19th and 20th centuries. It is free to search online. If you saved a Passenger ID before April 1, 2026, search by name again: the Foundation says those IDs no longer work.
- FamilySearch. Its free collection “New York Passenger Lists, 1820-1891” has an index and images. Search it at familysearch.org with a free account.
- The National Archives. It holds passenger arrival records from foreign ports from about 1820 (with gaps).
Search by surname first. Then try spelling variants. Try the first name alone with the year and the home town. If the name still fails, search for a sibling or a spouse. Families often traveled in stages. Checked October 2026.
You can also visit the island itself. Our Statue of Liberty and Ellis Island visitor guide explains the ferry and the museum.
Step 3: Use the Federal Census to Find the Address
The US census has been taken every ten years since 1790. Because of a 72-year rule, the most recent census open to the public is 1950 (National Archives). The 1950 census opened on April 1, 2022.
A census page gives you a street address. It lists everyone in the home. It gives ages, jobs and birthplaces, and the 1900 to 1930 censuses give the year of immigration. It often shows lodgers too. In a crowded tenement, lodgers were common.
One gap needs a warning. Most of the 1890 population schedules were badly damaged by a fire in January 1921 (National Archives). Use city directories and newspapers for that decade instead.
FamilySearch offers free census images and indexes with a free account. Large paid sites offer the same records. Many public libraries give free access to the paid sites inside the library. Ask at your local branch.
Once you have an address, you can look at the building itself. Our guide to New York in 1910 and tenement life shows what those rooms were like. It lists rents, wages and work hours.
Step 4: Order New York City Vital Records
Births, marriages and deaths each leave a record. These records give parents’ names, ages and addresses. They sometimes give a mother’s maiden name. That one detail can open a whole new branch of the tree.
The NYC Municipal Archives, run by the city’s Department of Records and Information Services, hold the older city records. Its free website Historical Vital Records of NYC gives access to millions of digitized birth, death and marriage records from 1855 to 1950. You can search, browse, download or order certified copies.
Later records sit elsewhere: births after 1909 and deaths after 1950 with the NYC Department of Health, and marriages after 1949 with the Office of the City Clerk (Municipal Archives genealogy page). Check each office’s own page for who can order and what it costs.
Remember the 1898 line. Search Manhattan and Brooklyn separately for earlier events. The Bronx, Queens and Staten Island have their own histories too. A birth in Williamsburg in 1890 sits in a Brooklyn file, not a Manhattan one.
The Municipal Archives also hold the tax photographs that document every New York City building in the 1940s and the 1980s. You can see the house your family knew, or one very close to it. Few records feel as personal as that one.
Step 5: Look for Citizenship and Court Records
Many immigrants became US citizens. Their papers can give a birth date, a home town and the date of arrival. Before September 27, 1906, any “court of record” (municipal, county, state, or federal) could grant citizenship. Federal court naturalization records for New York are now held by the National Archives at Philadelphia, not in Manhattan: the National Archives says “all naturalization records will be moved to Philadelphia.” Its New York holdings list links the records you can already view online at FamilySearch. Source: National Archives. Checked October 2026.
Wills offer another route. The Surrogate’s Court in each county handles the probate of wills. A will names heirs, and heirs name each other. Church and synagogue records add baptisms, weddings and burials. Many parishes still keep their own books. A polite letter to the parish office often brings an answer.
Step 6: Read What Your Ancestors Read
Old newspapers bring a name to life. You may find a wedding notice, a shop advertisement or a court case. You may even find a small fire in the family’s building.
- Chronicling America. The Library of Congress runs this free archive of old US papers.
- Fultonhistory.com. A long-running site of scanned old newspapers, many from New York State.
- The Brooklyn Newsstand. The Brooklyn Public Library offers the full run of the Brooklyn Daily Eagle (1841-1963) online, free. The Center for Brooklyn History helps with local questions.
- Foreign-language papers. Italian, Yiddish, German, Polish and Chinese papers all served the city. They often name families that English papers ignored.
City directories help too. They list names, jobs and addresses year by year. If a name drops out of the directory, the family may have moved or died. Both clues matter.
Where to Do Your Research in Person
Some answers sit in the archives of the city itself. These are the main stops:
- New York Public Library. The Stephen A. Schwarzman Building on Fifth Avenue at 42nd Street has a genealogy division. It is the Milstein Division, in Room 121. Entry is free, and staff can guide your research. A library card is needed to request most print materials.
- Center for Jewish History. The center sits at 15 West 16th Street. It houses the YIVO Institute for Jewish Research and the Ackman & Ziff Family Genealogy Institute. YIVO’s Miriam Weiner Genealogy Collection covers towns in Eastern Europe.
- NYC Municipal Archives. 31 Chambers Street, by appointment. This is the home of the city’s older vital records and the tax photographs.
- Center for Brooklyn History. The Brooklyn Public Library’s research library, free and open to all.
- Tenement Museum. The museum at 103 Orchard Street runs guided tours of two historic buildings, 97 and 103 Orchard Street, and tells the stories of real immigrant families who lived there.

Find the Neighborhood Your Family Called Home
Once you have an address, the story changes. You no longer search for a name. You search for a place. Each immigrant group clustered in its own streets. The street often tells you where to look next.
- Irish families often began near the docks. Read about Five Points and the first Irish New York.
- Jewish families from Eastern Europe filled the tenements east of the Bowery. See the Lower East Side Jewish story.
- Italian families gathered around Mulberry Street. See Little Italy in Manhattan.
- Chinese families built a community near Mott Street. See Chinatown, Manhattan.
- Greek families settled across the river in Queens. See Astoria, Queens.
- Black families arrived from the South in the Great Migration. See Harlem.
Add DNA to the Paper Trail
A DNA test cannot replace records. It can confirm them. It can also link you to cousins you never knew. Those cousins may hold the photo or the letter you need.
Treat results as clues. Match lists make sense only with a family tree. Share your tree with close matches. Ask them about the New York branch of their line.
Plan Your Heritage Visit
When the research is done, go and stand there. Walk the block from the census page. Find the church where the wedding took place. Take the ferry to Ellis Island. Bring a printed copy of the manifest. Visitors tell us this moment stays with them.
Pick a day outside peak summer. Wear good shoes. Photograph the street signs and the building numbers. Write down what you see, while you still feel it.
