Kalvoinen

Kalvoinen is a Finnish surname of Finnish origin, derived from the word *kalvo*, meaning "skin" or "leather." It is primarily associated with the Finnish-speaking regions, particularly in the provinces of Ostrobothnia and Karelia, where it has historical significance. The name may also have ties to the profession of a tanner or leatherworker, as the word *kalvo* can refer to the outer layer of animal hides.

The surname is relatively uncommon but has been documented in various Finnish archives, often linked to families with traditional occupations in the leather industry. Over time, the spelling may have varied slightly due to dialectal influences or typographical changes, though *Kalvoinen* remains the most widely recognized form.

In modern usage, individuals with the surname Kalvoinen may be found across Finland, though the name is more concentrated in rural and historical areas. It is also occasionally encountered in Sweden, particularly among Finnish-speaking communities, due to historical migration patterns.

The surname does not have a widely recognized cultural or historical figure bearing it, but it reflects a connection to Finland’s heritage in craftsmanship and natural materials. For genealogical research, records from the 19th and early 20th centuries often list variations of the name, aiding in tracing family lineages.
