Sierpecki

Sierpecki is a Polish-language surname of toponymic origin. It most commonly signals origin from a place named Sierpc, a town in central Poland, though the root and the adjectival suffix -cki appear in several related place-based surnames. The masculine form is Sierpecki, the feminine form is Sierpecka, and the plural form is Sierpeccy. As with many Polish -cki surnames, the name typically reflects an ancestral link to a specific locality.

In use, Sierpecki identifies individuals and families connected to Polish geographic origin. The surname is found among people in Poland and within Polish diaspora communities abroad, including in North America and Western Europe. In non-Polish contexts, the spelling may be transliterated or anglicized in various ways, but the base form Sierpecki is still recognizable as Polish in origin. Like other toponymic names, it emerged through medieval and early modern naming practices that linked a family to a particular place.
