The surname of the wife after a wedding in Italy

The Use of Maiden Names in Italy and Its Importance for Genealogy

During the 19th and early 20th centuries, at the height of the massive Italian emigration to America, there was a deeply rooted tradition in Italy regarding surnames: women retained their maiden names throughout their lives, even after marriage.

Why Italian Women Kept Their Maiden Name

This practice was not only a cultural custom but also a formal regulation established by the Italian civil registration system. According to the laws in force at the time, a woman’s legal identity remained permanently linked to her birth surname, without changing upon marriage.

In fact, under the Italian Civil Code (Article 143 bis), women who marry keep their family surname. They have the option — not the obligation — to add their husband’s surname after theirs, but they cannot legally replace their own surname with their husband’s.
Even today, non-Italian citizens who marry in Italy do not change their surname by marriage under Italian law, and they must continue using their original surname in all official documents, ID cards, and passports throughout their lives.

This tradition sharply contrasts with practices in countries such as the United States, where it is common for women to adopt their husband’s surname after marriage, altering their legal identity.

How This Affects Italian Genealogy Research

In official documents — especially civil records of birth, marriage, death, and emigration — women were, in the vast majority of cases, registered under their maiden name.
However, exceptions can occasionally be found, especially in parish registers, local census records, or less formal documents, where women might appear associated with their husband’s surname or identified through relational expressions (“wife of…”). These variations often reflected social customs, registration habits, or local practices rather than strict legal rules.

For genealogists, understanding this specificity is essential.
For example, if you find a woman listed as Lucia Sanestro, you can immediately infer that her father’s surname was Sanestro. This simplifies the search for parental lines in genealogical research.
However, it is also important to be aware that during genealogical investigations, one may encounter cases of children who were not formally recognized by their parents.
This could happen for various reasons: they might have been abandoned, or their legal registration might have been affected by the historical conflicts between the Catholic Church and the Italian state.

Furthermore, at that time, children always carried their father’s surname, with no legal possibility of using the mother’s surname or combining both names, as modern laws sometimes allow.
This structure makes it relatively straightforward to follow paternal lines but requires careful attention to correctly trace maternal ancestry through women’s birth names.

Final Considerations

In summary, the retention of a woman’s maiden name in Italy was both a cultural tradition and a legal requirement, even though occasional practical exceptions can be found in historical records.
For those researching the history of Italian emigrants to America, knowing these naming customs is crucial to reconstructing family trees accurately and preserving the authentic identity of their ancestors.
