From nickname to law: how Polish surnames formed (14th–19th c.)

1. Introduction

The modern two-part naming system, consisting of a given name (nomen) and a surname (cognomen), is, from the perspective of the history of the Polish language, a relatively young phenomenon. Although today the surname is the basic official identifier of every citizen and evokes strong associations with identity and blood ties, its origin is a complex, centuries-long sociological, legal, and linguistic process. The formation of Polish surnames was a gradual evolution, lasting from the late Middle Ages until the turn of the 18th and 19th centuries.

What is critically important from the standpoint of modern genealogical and genetic research is that this evolution meant that a shared surname is by no means a synonym for kinship. In old Poland, a surname was a legal, administrative, geographic, or descriptive construct - not a record of DNA.

2. One-name identity - the Old Polish starting model

In the early Piast era (up to the 12th century), the basic and essentially only way to identify an individual was the given name. This resulted from the fact that the population was sparse and communities were closed and small. At that time, a set of traditional, pagan two-part names existed (e.g. Wojciech, Bogumil), assigned to knighthood, alongside one-part names (e.g. Jez) characteristic of lower classes.

With Christianization and the development of settlement under German law in the 13th century, this pool shrank drastically. Christian calendar names (Jan, Piotr, Pawel) dominated society. This phenomenon led to an "identification crisis": too many Jans or Piotrs appeared in a single village for the given name alone to distinguish them in everyday relations.

3. The formation of additional identifiers (13th–15th c.)

The growing need to identify a specific person meant that, alongside the baptismal name, a second designation began to be used. It was purely descriptive in nature and, at that time, not yet hereditary. Second designations were formed in four main categories:

• Patronymic - indicating the father (e.g. Pietraszek - son of Piotr, Janowicz).
• Toponymic (place-based) - indicating a place of origin or holding (e.g. "z Grabowa" - from Grabow).
• Occupational - derived from trades (e.g. Kowal - blacksmith, Mlynarz - miller).
• Nickname-based - referring to physical features (e.g. Bialek - pale one, Broda - beard).

4. The role of the Church and the Council of Trent

An enormous catalyst for the standardization of naming was the Council of Trent (1545–1563). It introduced, within the Catholic Church, an absolute obligation for parish priests to keep parish registers (of baptisms and marriages). This decree forced clergy to precisely identify parishioners. Parish registers became the first "laboratory" for the surnames of the lower social classes. Priests, needing to distinguish peasants sharing the same given name, often "assigned" designations themselves, entering them into the registers at their own discretion, based on the person's trade or place of residence (e.g. Joannes dictus Sowa, meaning "Jan called Owl").

5. Crystallization of surnames among the nobility (15th–16th c.)

Among the Polish magnates and knighthood, additional designations began to take on a hereditary character much earlier, already in the 15th century. This mechanism was tied to the hardening of the estate-based social order and the need to prove one's rights to land (the so-called "nagana szlachectwa" - challenge to nobility status).

In the 16th century, the pattern of the toponymic surname became entrenched. It was formed by adding the suffix -ski or -cki to the name of an owned village. A nobleman Jan from Tarnow became Jan Tarnowski. The dominance of this model coincided with the so-called golden age of the nobility, and the adjectival-form surname became a symbol of prestige.

6. The illusion of common origin: why a shared surname does not mean blood ties

The system of surname formation favored the emergence of identical forms among people who were entirely genetically unrelated to one another. This resulted from several fundamental mechanisms:

• Repetitiveness of toponymy and shared land ownership: surnames ending in -ski were formed from village names. Poland, however, had dozens of localities with names such as Dabrowa, Grabow, or Wola. A nobleman from Dabrowa in Wielkopolska was called Dabrowski, and so was an unrelated nobleman from a Dabrowa in Mazovia. Moreover, when a single village was divided into so-called noble shares, representatives of several unrelated knightly families acquiring plots there would, over time, begin writing themselves under a shared surname derived from that same village.
• Peasants taking on surnames: in the feudal system, a peasant was bound to the land. Priests and officials often identified a peasant through the person of his owner. A peasant working for the Zamoyski family would be recorded as "Jan od Zamoyskich" (Jan of the Zamoyskis), which ultimately shortened to "Jan Zamoyski." A huge portion of today's holders of great, magnate surnames are descendants of former subjects who adopted the surname of their lords.
• The universality of trades and nicknames: a Kowal (blacksmith) from Gdansk and a Kowal from Krakow shared no common ancestors - they were connected only by occupation.

7. Townspeople and peasants - evolution and imitation

In the urban environment, second designations began to stabilize at the turn of the 16th and 17th centuries. Wealthier patricians, however, readily adopted the noble model, artificially adding the suffix -ski to their surnames. The phenomenon of "ennobling" a surname (e.g. changing a craftsman named Skowron to Skowronski) was meant to erase plebeian roots.

The greatest fluidity prevailed in the villages. The same peasant could be recorded one year as Kowalczyk (after his father's trade), and in another year as Wojcik (if he became the village mayor). There was no rule of stable inheritance.

8. Women in the naming system: maiden and married variants

A phenomenon unique on a European scale within the Polish anthroponymic system, resulting from the patriarchal structure of society, was a developed system of suffixes denoting a woman's marital status.

Wives received the suffixes -owa or -ina / -yna (the wife of Kowal was Kowalowa, the wife of Zareba was Zarebina). Daughters (unmarried) were identified with the suffixes -owna or -anka (the daughter of Kowal was Kowalowna, the daughter of Zareba was Zarebianka).

This system clearly showed that a woman in old Poland legally "belonged" first to her father, and after marriage, to her husband. Only in the 20th century did these forms begin to disappear from official use in favor of the male form.

9. State coercion: assigning surnames during the partitions (including to Jews)

It was only the Age of Enlightenment and the partitions of the Polish Commonwealth that finally stabilized the surnames of peasants and Jews. The administrations of the partitioning powers (especially Prussia and Austria), in order to streamline tax collection and military conscription, imposed bureaucratic rigor. Peasants were forced to adopt permanent surnames.

A particularly dramatic and fascinating process concerned the Jewish community. Until the end of the 18th century, Jews in Poland used the traditional patronymic system (e.g. Izaak ben Abraham). The partitioning governments issued patents forcing them to adopt permanent, hereditary surnames. Wealthier Jews could purchase attractive, poetic compound surnames (e.g. Rosenthal - valley of roses, Silberstein - silver stone). Poorer ones were assigned surnames arbitrarily by officials, often from city names (Warszawski), colors (Schwarz, Weiss), or common nouns.

10. Double-barreled surnames and the defense of identity in the 19th century

The 19th century brought yet another phenomenon - a fashion for double-barreled surnames among the Polish nobility. When the partitioning powers (especially the Russian Empire, after the fall of the national uprisings) began strictly verifying noble status (so-called legitimization of nobility), and peasants massively adopted the -ski ending, the old nobility felt the need to distinguish itself.

People began massively attaching coat-of-arms names or Old Polish bynames to their family surname. This is how today's double-barreled forms arose, such as Korwin-Mikke, Slepowron-Wroblewski, or Biberstein-Starowieyski. This was meant to seal the "antiquity" and authenticity of the lineage in the face of the erosion of old estate barriers.

11. The contribution of foreign languages

The richness of the Polish surname pool was significantly shaped by the multinational structure of the First Polish Republic:

• Eastern influences (Ruthenian and Lithuanian): brought patronymic naming with the suffixes -owicz / -ewicz (e.g. Mickiewicz, Sienkiewicz).
• Western influences: urban settlement left behind surnames of German origin (Szulc, Miller), often phonetically Polonized (e.g. German Hammer transformed into Hamerski).

12. Summary

The process of forming the Polish anthroponymic system is a fascinating lesson in social history. Beginning out of the pragmatic necessity of distinguishing neighbors from one another, it evolved into a complex hereditary system. The nobility created an elite surname model, which was gradually democratized by the lower estates. Legal and administrative coercion by the partitioning states, ecclesiastical regulations, and patriarchal grammar ultimately shaped the system we use today.

The key lesson from this analysis remains the fact that a surname in old Poland was purely a legal, property-based, or neighborly category. Modern genetic genealogy mercilessly proves that thousands of people bearing the same, proudly sounding surname are, in reality, descendants of dozens of entirely unrelated knightly, peasant, and burgher families.
