If your Italian ancestors came from Trentino, you belong to one of the most distinctive diaspora communities in history. Millions of people across Brazil, Argentina, Australia, and the United States trace their roots to this alpine region. This guide shows you how to trace your family in Trentino, step by step.
Trentino sits in the far north of Italy. It borders Austria. Its history shaped how records were kept — and that changes how you research. But the records are rich. This guide covers everything you need to plan your heritage journey.

Until 1918, Trentino was part of the Austro-Hungarian Empire. That changes everything about your research. Italian civil records (Stato Civile) in this region only began in 1923. Before that date, the Austrian system applied. Records were kept by the church. Some were written in German as well as Italian.
This is different from southern Italy, where civil records go back to 1809 or 1866. If your Trentino ancestors left before 1920, you will be working with church records and Austrian-era documents. They exist. They are detailed. But you need to know where to look.
Post-1918, Italy took over the region. Full Italian civil registration began from 1923. Records from this point are in Italian and follow the same structure as the rest of Italy.
The Emigration Story: Where Trentino Families Went
The great emigration from Trentino ran from roughly 1876 to 1930. Poverty, scarce land, and failed harvests drove hundreds of thousands of families to leave the Dolomite valleys.
Brazil received the largest wave. Around 2.5 million Brazilians today claim Trentino ancestry. They settled mainly in Santa Catarina, Rio Grande do Sul, and São Paulo state. The valleys they came from include Val di Non, Val di Sole, Valsugana, and Val Rendena.
Many of these Brazilian families still speak Talian — a dialect that blends old Venetian and Trentino Italian. Their grandparents brought it from the valleys over 130 years ago. It survives to this day in isolated communities in the Brazilian interior.
Argentina was the second main destination. Buenos Aires, Rosario, and Córdoba all have families with Trentino roots. Many arrived between 1880 and 1910.
The United States also received large numbers. New York, Boston, Chicago, and Cleveland had active Trentino communities. Mining towns in Pennsylvania and Colorado attracted men looking for work.
Australia welcomed Trentino emigrants too. The Riverina region of New South Wales has communities with direct Trentino ancestry.
The emigration period is key for your research. Most families left between 1876 and 1914. If your ancestor appears in a ship manifest from this period, their village of origin is often recorded.

What Records Exist for Trentino Research
Civil Records (Stato Civile)
Italian civil registration in Trentino began in 1923. Records include births, marriages, and deaths. You can request certified copies from the Comune (town hall) of your ancestral village. Some comuni hold records going back to Austrian civil registration from 1870.
Church Parish Records (Registri Parrocchiali)
Catholic parish records in Trentino are among the oldest in Europe. Trento was the site of the Council of Trent (1545–1563). As a result, the diocese required strict record-keeping from that period onward.
Parish records include baptisms (battesimi), marriages (matrimoni), and burials (sepolture). Most date from the mid-1600s. Some go back to the 1500s. These are held at the original parish church or at the Archivio Diocesano Tridentino.
The Antenati Portal
The Italian National Archives portal Antenati hosts digitised civil records. Trentino records on this platform are limited due to the late start of civil registration. But it is worth checking your ancestor’s comune to see what is available.
For pre-1923 records, you will need to contact archives in Trento or Austria directly.
Austrian Archives
Because Trentino was Habsburg territory, some records are in Austria. The Österreichisches Staatsarchiv (Austrian State Archives) in Vienna holds military, nobility, and government records. The Tiroler Landesarchiv in Innsbruck also holds regional documents from the Austrian period.
If your ancestor served in the Austrian army or held property, these archives may have records that Italian archives do not.
The Main Archives in Trentino
Archivio di Stato di Trento — This is the main state archive for the province. It holds civil records, land records, and notarial documents. You can visit in person or contact them by email to request record searches.
Archivio Diocesano Tridentino — This is the Catholic diocesan archive. It holds the oldest parish records in the region. For pre-1800 research, this archive is essential. It is located in Trento city centre.
Individual Parish Archives — Many original records remain with the local church. Contact the parish priest (parroco) of your ancestral village. Small Trentino parishes often hold records going back to the 1600s.
Archivi Comunali — Each comune has its own archive. These hold civil records from 1923, land registries, and local history documents. Municipal staff are often helpful with genealogy requests. Write to them in Italian if you can.
For more detail on how to access Italian archives across all regions, our step-by-step guide walks you through the full process.
How to Find Your Ancestral Village in Trentino
You may already know your family’s village. Many Trentino emigrant families recorded their exact comune in ship manifests, naturalisation papers, or family documents.
If you do not know the village, start with these steps.
Step 1: Check ship manifests. Ellis Island passenger records list the town of origin in Italy. Ancestry.com and FamilySearch both hold these records. Search for your ancestor’s full name and approximate arrival year.
Step 2: Check naturalisation records. US naturalisation papers from the early 1900s often list the exact birthplace in Italy. These are in the NARA (National Archives and Records Administration) databases.
Step 3: Search FamilySearch. The LDS Church has digitised many Trentino parish records. Search FamilySearch.org for your surname combined with “Trento” or “Trentino.”
Step 4: Contact the Comune directly. Once you have a village name, email the municipio (town hall). Write in Italian if possible. Most comuni are responsive to genealogy requests from diaspora descendants.
Our full guide to planning an Italian heritage trip to your ancestral town covers what to do once you have located your village.
Understanding Trentino Surnames
Trentino surnames reflect the region’s layered history. You will find names from three main traditions.
Italian surnames from the Roman and medieval period include Rossi, Ferrari, Martini, and Conti. These are common across Italy and do not point specifically to Trentino.
Germanic surnames from the Austrian period are a strong signal of Trentino origin. Names like Mittempergher, Brugnara, Kessler, and Oberprantacher are rare elsewhere in Italy. If your surname sounds German but your family was Italian, Trentino may be your region.
Surnames ending in -er, -ner, or -er often indicate Alpine or Austrian heritage: Moser, Gruber, Brunner, Siller.
Adapted surnames in the diaspora. Families who emigrated to Brazil and Argentina often changed their surnames. Mittempergher became Mitterperger in Brazil. Brugnara became Brunara. If your family name looks like a garbled version of a German word, check Trentino records.

A 7-Day Heritage Itinerary for Trentino
If you are planning a trip to trace your Trentino roots, here is a suggested route.
Day 1–2: Trento. Base yourself in Trento, the regional capital. Visit the Archivio di Stato di Trento to start your record search. The city itself rewards exploration. The Castello del Buonconsiglio and the Cathedral of San Vigilio sit at the heart of the old town. Walk the streets your ancestors walked when they came to the city for markets or church administration.
Day 3: Your Ancestral Village. Travel to your family’s comune. For Italian-Brazilians and Italian-Americans with Trentino roots, this day is often the most emotional. Visit the town hall for civil records. Find the parish church and ask about baptism records. Walk the streets. Look at the landscape. Many visitors describe this as the moment the family story becomes real.
Day 4: Valsugana or Val di Non. These were two of the main emigration valleys. Val di Non is famous for its apple orchards. Valsugana runs east from Trento toward the Veneto border. Both valleys sent thousands of families to Brazil and Argentina in the late 1800s. A day driving through these valleys brings the emigration story to life.
Day 5: Rovereto. Visit the town of Rovereto, south of Trento. It has a strong local heritage culture. The Museo Storico Italiano della Guerra tells the story of Trentino during the First World War — a period when many families were caught between the Italian and Austrian sides.
Day 6: The Dolomites. No heritage trip to Trentino is complete without seeing the landscape your ancestors knew. Drive into the Val di Fassa or up to the Tre Cime di Lavaredo. These mountains were the backdrop to daily life for generations of Trentino families. The scale of them is humbling.
Day 7: The Cemetery. Visit the local cimitero (cemetery) of your ancestral village. Trentino cemeteries are well-maintained. Headstones often carry exact birth and death dates. Photograph every stone in your family’s section. This is often where diaspora visitors find names they recognise from family trees.
For a broader Italian heritage travel framework, our 7-day Italian ancestry itinerary covers how to plan across multiple regions.
The Emotional Story of Trentino Emigration
The emigration from Trentino was not a choice made lightly. The valleys were poor. Land was divided among too many children. Harvests failed. Young men left first, sending money home. Some never returned.
Families from the comune of Pergine Valsugana, east of Trento, gathered at dawn to say goodbye at the railway station. They carried a single trunk. They spoke Trentino dialect. They knew almost nothing of Brazil or Argentina.
What they carried was memory. They planted the same vegetables in new soil. They kept the same saints’ feast days. Every December, families in São Paulo state still make zelten — a dense fruit cake with walnuts, figs, and raisins. Their great-great-grandmothers made the same cake in Trentino valleys 130 years ago. The recipe never changed.
The Talian dialect — a form of old Venetian mixed with Trentino words — is still spoken in rural communities in Rio Grande do Sul. Children learn it. Old men use it as their first language. It is the sound of a world that no longer exists in Italy but lives on in South America.
When you visit your ancestral village in Trentino, you are completing a circle that began over a century ago. You are returning to the place your family left. The mountains are still there. The parish church is still there. And in the archive, in careful handwriting, is the record of your ancestor’s birth.

Frequently Asked Questions
What records exist for tracing Italian ancestry in Trentino?
Italian civil records (Stato Civile) in Trentino begin in 1923. Before that, Austrian church parish records apply. These go back to the 1500s in many parishes. They are held at the Archivio di Stato di Trento, the Archivio Diocesano Tridentino, and individual parish churches.
Why are Trentino genealogy records different from other Italian regions?
Trentino was part of the Austro-Hungarian Empire until 1918. Pre-1923 records follow Austrian formats. Some are in German. Some are held in Austrian archives in Vienna and Innsbruck. This is very different from southern Italy, where Italian civil records often begin in the early 1800s.
How do I find my ancestral village in Trentino?
Start with ship manifests on Ellis Island or Ancestry.com. These often list the exact town of origin. Naturalisation papers from the early 1900s are also useful. FamilySearch.org has digitised many Trentino parish records you can search for free.
Can I apply for Italian dual citizenship through Trentino ancestry?
Yes. Italy’s jure sanguinis law allows citizenship through ancestry regardless of how many generations back. Trentino ancestry qualifies. You will need birth, marriage, and death certificates for each generation back to your Italian-born ancestor. Our dual citizenship guide explains the process in full.
How many people worldwide have Trentino ancestry?
Around 2.5 million people in Brazil alone claim Trentino ancestry. Argentina, the United States, and Australia also have large communities. Many Brazilian families of Trentino descent still speak Talian, a dialect preserved from the emigration period.
What language were old Trentino records written in?
Post-1923 records are in Italian. Pre-1923 church records may be in Latin, Italian, or German. Austrian civil records from the 1800s are often in German. A genealogist who reads German and Italian is helpful for this research.
