Name and Surname Discrepancies in Italian Citizenship by Descent: Causes and Solutions

One of the most common practical obstacles in Italian citizenship by descent applications is the discovery that the name or surname of the Italian ancestor — as it appears in Italian civil registry records — does not match the name recorded in the documents from the country of emigration. Sometimes the difference is minor: a vowel dropped, a consonant changed, a double letter simplified. In other cases, the name has been completely transformed — an Italian Giuseppe became a Joseph, a Ferrarini became a Ferrini or even Ferrari.

These discrepancies are not rare exceptions — they are an extremely widespread phenomenon affecting thousands of citizenship by descent applications from South America, North America and Australia, where large waves of Italian emigration occurred between the late 19th and mid-20th centuries. Understanding why they occurred, how Italian courts and consulates approach them, and what legal tools are available to resolve them is essential for any applicant who encounters this problem.

Why Italian Names Were Altered in Emigration Countries

The alteration of Italian emigrants’ names and surnames in their destination countries was not typically the result of a single deliberate act. It arose from the interaction of several historical factors that were largely outside the emigrants’ control.

Illiteracy and Communication Barriers

The Italian emigration waves of the late 19th and early 20th centuries included a very high proportion of people who were illiterate or had minimal education. When Italian emigrants arrived at ports of entry — Ellis Island in New York, the Port of Santos in Brazil, the Port of Buenos Aires in Argentina — they were processed by immigration officials who typically did not speak Italian. The emigrants could not read or correct the records being made about them.

In this situation, the name recorded in the destination country’s civil registry depended entirely on the official’s ability to phonetically render an Italian name they had never heard before — often in a language system with different phonetic conventions. Errors made at this initial registration frequently propagated through all subsequent documents as the erroneous version became the established spelling for the family.

Phonetic Adaptation to the Language of the Destination Country

Even where the initial registration was relatively accurate, the name often underwent further adaptation over time as the family integrated linguistically and socially into the destination country. Italian names were systematically adapted to the phonetic conventions of the local language:

• In English-speaking countries, Italian names were anglicised: Giovanni became John, Giuseppe became Joseph, Vincenzo became Vincent
• In Spanish and Portuguese-speaking countries, the adaptation was often less dramatic but still produced variations: Italian double consonants were often simplified (Ferraro became Feraro), endings were modified to conform to local patterns
• Surnames with typically Italian endings (-ini, -etti, -elli) were often shortened or modified

The phonetic distance between Italian and the destination country’s language was a major determinant of the degree of alteration. Alterations were generally more dramatic in English-speaking countries (where the phonetic system is most different from Italian) and less dramatic in Spanish and Portuguese-speaking countries (whose phonetics are closer to Italian).

Multiple Given Names and the Prevalence Problem

Italian naming conventions of the 19th century commonly assigned multiple given names to a child — for example, Giuseppe Antonio Maria. In Italy, all names were recorded in civil registry documents. In emigration countries, officials often recorded only one of the names — frequently not the first — creating an apparent discrepancy. A person recorded as Giuseppe Antonio Maria Rossi in Italian records might appear as Antonio Rossi or Maria Rossi in Brazilian or American records.

Deliberate Name Changes

In a smaller number of cases, the alteration was deliberate. Some emigrants wished to create a completely new identity in the destination country — to leave behind economic difficulties, family conflicts or, in some periods, political persecution. In these cases, the alteration was intentional and the link between the Italian original and the emigration country record must be established through indirect evidence.

How Name Discrepancies Affect Citizenship Applications

In a citizenship by descent application, each document in the chain — from the Italian ancestor’s birth certificate through every generation to the applicant — must consistently identify the same person. A discrepancy in a name or surname between two documents creates a gap in the chain: the competent authority (consulate, municipality or court) cannot automatically conclude that the person named in the Italian records is the same person whose descendants are now claiming citizenship.

The severity of the problem depends on the nature of the discrepancy:

• Minor orthographic variations (a single letter, an accent, a double/single consonant) are generally handled with flexibility by Italian courts and consulates, which recognise them as transcription variants of the same name
• Different given names where the Italian ancestor is recorded under one name in Italian records and another in emigration country records require more substantial evidence of identity
• Significantly altered surnames that do not obviously derive from the Italian original may require formal legal proceedings to establish the connection

The Legal Framework: Presumptions Under Article 2727 of the Civil Code

Italian courts handling citizenship by descent cases — including both administrative proceedings and judicial cases — have developed a flexible approach to name discrepancies, relying heavily on the legal tool of presumptions.

Under Article 2727 of the Italian Civil Code, a presumption is the inference that the law or the judge draws from a known fact to establish an unknown fact. In the context of name discrepancies, courts use the following approach:

• The surname is treated as a legal presumption for establishing family identity — where a surname in emigration country records is clearly a phonetic variant or derivative of the Italian surname, this creates a presumption that the two records refer to the same family
• Simple presumptions (free judicial inference) are used where the overall body of evidence — combined dates of birth, names of parents, places of origin, other contemporaneous documents — consistently points to the same person, even if the names are recorded differently

This presumption-based approach reflects the practical reality that strict documentary requirements would make it impossible to verify genealogical chains going back 100 or more years, where name alterations were systematic and widespread. Courts recognise that requiring perfect orthographic consistency across documents produced in different countries, languages and bureaucratic systems over many decades is unreasonable.

The Ministerial Circular No. 397/2008: A Critical Development

Before the issuance of Ministry of the Interior Circular No. 397 of 2008, Italian civil registry officials applied a strict rule when transcribing foreign birth certificates of Italian citizens: they recorded only the surname assigned under Italian law (following the paternal line), disregarding any different surname the person had been assigned at birth in the foreign country.

This created significant rigidity in citizenship by descent proceedings, because the Italian administrative authorities were then confronted with documents showing different surnames and were required to treat this as a discrepancy requiring formal resolution.

Circular No. 397/2008 changed this approach significantly. It directed civil registry officials that, when transcribing the foreign birth certificate of an Italian citizen, they should record the surname as indicated in that foreign birth certificate — not impose the Italian paternal surname rule. This applied both to new transcriptions and, in principle, to existing transcriptions that had been made incorrectly under the old approach.

The circular also clarified that this principle applies to cases involving citizenship of non-EU countries — specifically mentioning South American countries — and that the paternal surname rule does not override the right of the individual to have their actual registered name recognised in Italian documents.

The practical effect for citizenship by descent applicants is significant: where a discrepancy between the Italian and the foreign surname arose from the old administrative practice of imposing the Italian paternal surname, this can be addressed through the rectification procedure rather than being treated as an obstacle to citizenship recognition.

Rectification of Civil Registry Records: DPR No. 396/2000

Where an error or discrepancy exists in Italian civil registry documents — or where a foreign document contains an error that can be traced back to a mistake in the original Italian registration — a formal rectification can be requested. The legal basis is Presidential Decree No. 396 of 2000, which governs Italian civil registry matters.

Rectification can be either administrative (where the error is obvious and unambiguous and the civil registry official can act directly) or judicial (where the matter is contested or requires a court determination). In the citizenship by descent context, judicial rectification proceedings are often required where the discrepancy is significant and the link between the two versions of the name is not immediately obvious from the documents alone.

The same rectification mechanism exists in many emigration countries — Italy’s major destination countries (Brazil, Argentina, the United States) all have procedures for correcting civil registry records. Where a discrepancy originated from an error in the emigration country’s records, the correction should be sought from the competent authority in that country.

Practical Approaches to Resolving Name Discrepancies

In practice, the approach to a name discrepancy in a citizenship by descent case depends on its severity and the procedural route being used:

• Administrative route (consulate or municipality): the applicant presents all available evidence of the identity connection — a certificate of congruity of personal data (certificato di congruità dei dati anagrafici) issued by the relevant foreign authority, or other contemporaneous documents that consistently link the two versions of the name. The competent authority assesses the evidence and, in most cases of minor or moderate discrepancies, accepts the presumption of identity
• Judicial route: courts have greater flexibility in assessing evidence and applying presumptions. In judicial proceedings, a technical expert can be engaged to analyse the phonetic derivation of the name variant and provide a formal opinion on the connection between the two versions. This is particularly useful for cases involving dramatic anglicisations or complete name translations
• Formal rectification: where the discrepancy can be traced to a specific error in a document (Italian or foreign), a formal rectification through the competent civil registry authority or court should be sought. This produces a corrected document that resolves the discrepancy at source

Frequently Asked Questions

My ancestor’s surname appears as two different spellings across the documents. Will this prevent my citizenship application?

Not necessarily. Minor spelling variations in surnames — particularly those that reflect straightforward phonetic adaptation from Italian to another language — are routinely handled by Italian courts and consulates through the presumption framework. The key is to present all available corroborating evidence that consistently links the two versions to the same person (matching dates of birth, parents’ names, places of origin, etc.). A citizenship by descent lawyer can assess the specific discrepancy and advise on the most effective approach.

My ancestor’s first name in Italian records is completely different from the name used in all foreign records. Is this a problem?

This type of discrepancy — where a given name has been translated or replaced rather than simply adapted phonetically — requires more substantial evidence to bridge. The most effective approach is to gather all contemporaneous documents from the period of emigration that link both names to the same person, and to establish the pattern of name substitution (for example, by demonstrating that the given name used in the foreign country was a standard equivalent or translation of the Italian name). In complex cases, judicial proceedings with expert evidence on name equivalencies may be the most reliable route.

Do I need to correct the discrepancy before submitting my citizenship application?

Not always. In many cases, the discrepancy can be addressed as part of the application itself by presenting explanatory evidence. However, where the discrepancy is significant and the competent authority is likely to reject the application without formal resolution, obtaining a certificate of congruity from the foreign civil registry or pursuing a formal rectification before submitting the application avoids the risk of rejection and the need to re-submit.

The non-naturalization certificate mentions a different name from the one in my citizenship documents. Does this invalidate it?

This is a common problem. A non-naturalization certificate that uses a different version of the name than the Italian records must be accompanied by supporting evidence that the two versions refer to the same person — for example, a certificate of name congruity or the inclusion of all known name variants in the search request. For this reason, it is important to ensure that any non-naturalization certificate submitted specifically covers all names, variants and aliases under which the ancestor may have been known. See our article on the non-naturalization certificate for Italian citizenship by descent for more detail.
