The Woman Who Did Not Change Her Name

The Historian’s Craft

When a historian working with genealogy examines an old document, the task is not simply to read what is written. It is also to ask what the conventions of the period made possible, expected or unusual. And one detail can leap from a certificate like a silent alarm: the mother’s name. The way a woman’s name appears in a record says, often, more about the truth of a family than any declaration recorded before a civil registrar or notary.

Let us begin with a truth that surprises nearly every Brazilian. In the Iberian Peninsula, a woman did not usually change her name on marrying. In Portugal, as in Spain, in the great majority of cases the wife kept her own surname all her life. There were exceptions, above all when she married a foreigner of Anglo-Saxon origin, among whom a wife taking her husband’s surname was the norm. Marriage did not make her lose her maiden name nor oblige her to take the husband’s. That is the tradition, and the parish records prior to the twentieth century confirm it on every page. The Portuguese woman was, on paper, who she had always been.

We Brazilians are direct heirs of Portuguese culture. One would expect us to follow the same rule. And yet we did the opposite. It is worth understanding why, because that is where the story becomes interesting.

Where the husband’s name comes from

The custom of the woman taking the husband’s surname did not originate in the Iberian naming tradition. In the English common-law world, the doctrine of coverture provides one important legal background for it: on marrying, a woman’s legal existence merged with her husband’s, to the point that she lost a separate legal identity of her own. Under this principle, the wife became, in practice, an extension of the husband, and taking his name was the natural symbol of that absorption. That legal and cultural framework, and not the Iberian one, helps explain the married woman who signs with her husband’s surname.

In Brazil, this habit entered elite culture through fashion and imitation. Over the nineteenth century, with the opening of the ports and independence, the elite turned its eyes to France and England as a measure of modernity and civilization. It was under French influence, and later in the climate of the Belle Époque, that the upper classes came to adopt the husband’s surname as a mark of distinction. What began as elite imitation spread, and in the first decades of the twentieth century it was already almost socially obligatory. The law came after the custom. The Civil Code of 1916, in force from 1917, established that the woman assumed, by marriage, the husband’s surnames. The Married Woman’s Statute, of 1962, reinforced the obligation. And it was only in 1977, with the Divorce Law, that Brazilian law made the change optional rather than compulsory. For more than half a century, in Brazil, changing one’s name on marriage was not an option; it was an imposition.

Note the consequence. While the Brazilian woman was obliged by law to change her name, the Portuguese woman went on, by the tradition and the law of her land, keeping her own. The two sides of the Atlantic moved in opposite directions at exactly the same time.

Those who had no surname

And there is a second trait, stranger still to our eyes. Many women, in Portugal, did not even carry a family surname. One might be called simply Maria José, Maria João, Maria da Purificação, Maria da Encarnação. These are not surnames. They are names of devotion, of religious consecration, added to the baptismal name. Women from ordinary families, especially, could go through their entire lives without a hereditary family surname, identified only by their devotion. Whoever does not know this reads Maria da Encarnação and sets off in search of an Encarnação family that never existed.

What the mother’s name gives away

Now join the two things, and you will have one of the most powerful keys of my craft. When I find a Portuguese man born on the other side of the sea who declares, in a Brazilian document, the name of his parents, and the mother, born in Portugal, appears carrying the husband’s surname, something does not add up. Under Portuguese naming conventions, that form of her name would be unexpected. One explanation I have encountered repeatedly is an immigrant recasting his family history in Brazilian terms, giving the family the appearance of legitimacy that the Portuguese record perhaps did not support. It is the same movement of which I spoke when I treated the art of starting over and the migrants who invented a father on arriving. The mother’s surname aligned with the husband’s is, often, the discreet signature of that reinvention.

That is why the historian cannot read the past with the eyes of the present. Whoever works with genealogy needs a strong sense of the historical context of each period, needs to understand the complexity of the society that produced that document. A name is not just a name. It is a portrait of what was permitted, expected and possible in that time and that place. To read a record without this understanding is like reading a letter in a language one does not master. The words are there, but the meaning escapes.

When the right name looks wrong

There is also the reverse mistake, and this one I hear from clients all the time. Often the immigrant was entirely accurate. He might state that his mother was Germana Ambrosina and his father Francesco Guirelli. The names are correct, each retaining their own surname, faithful to the tradition of the land of origin. And it is precisely there that the Brazilian client becomes concerned. Accustomed to seeing the wife carry the husband’s surname, he looks at those two names that do not match and concludes, distressed, that the couple was not married or that the child was born outside marriage, that the mother did not belong to that family.

That reaction is understandable. It is a natural reaction of one who reads the past with the eyes of the present. The person is not judging out of malice, only projecting onto an old document the custom he knows, the Brazilian one, and finding strange what is, in truth, entirely normal for a Portuguese, Spanish or Italian couple of that period. The mother’s name being different from the father’s indicates no irregularity. It is simply a Portuguese, Spanish or Italian family following the naming conventions of its time and place.

This is exactly where the difference between the non-specialist reader’s eye and the historian’s becomes clear. Where one sees a problem, the other sees the norm. Where one reads shame, the other reads tradition. The same document, the same line, and two opposite readings, one that invents a scandal that never was, and another that recognizes, with serenity, an ordinary couple of their time. To reassure a family, showing that those different names do not indicate any irregularity, is part of my work as much as finding a lost document.

The same sign, opposite meanings

And there is a caveat that is, itself, part of the method. This rule holds for the Portuguese, Spanish and Italian traditions, among which the woman kept her own name. It does not hold for all. In a family of German or English origin, the wife carrying the husband’s surname is what is expected, because it is her tradition. The same detail, the mother’s surname, means opposite things according to the origin of whoever wrote it. In an Iberian or Italian context, it is an alert. In a German or English context, it is the norm. Knowing how to tell one from the other is what separates a hurried reading from a historically grounded one.

In the end, all of this comes down to a simple idea. A name carries the history of the place it came from. The woman who did not change her name is not a picturesque detail. She is a witness. And when she appears in a document dressed in a name her tradition would never have given her, it is a sign that someone, at some moment, wished to tell the story another way. My work is to listen to what the true name still has to say.
