Swedish Byname

Before fixed hereditary surnames became common in Sweden, communities needed ways to distinguish the many individuals who shared common given names like Lars, Erik, or Anna. The tillnamn — literally 'added name' or 'additional name' — served this function. These bynames could describe physical appearance, occupation, place of origin, or a personal characteristic, and they functioned as informal identifiers rather than formal legal names.

Types of Tillnamn

Swedish tillnamn fell into several categories: locational names indicating where a person came from or lived (Lars från Berget — Lars from the hill); occupational names describing a trade (Anders Smed — Anders the blacksmith); descriptive names referring to physical traits (Stor-Erik — Big Erik, Röd-Märta — Red-haired Märta); and relational names identifying a person through a family connection (Prästens Anna — the priest's Anna). These categories correspond broadly to the types of fixed surnames that eventually emerged when the patronymic and byname system solidified into hereditary surnames.

Legacy in Modern Surnames

Many modern Swedish surnames began as tillnamn that became fixed through use over generations. Occupational bynames like Smed (blacksmith), Skräddare (tailor), and Snickare (carpenter) became surnames. Locational bynames contributed to the nature-surname tradition. The descriptive byname tradition also survives informally in Swedish culture through nicknames (smeknamn) used in everyday social contexts. Understanding tillnamn is essential for Swedish genealogists navigating records from the 16th through 18th centuries, where the boundary between byname and surname was often fluid.
