Petrov

The origin of the surname Petrov

Petrov means “son of Pyotr,” from the Greek for “rock.”

What kind of surname is Petrov?

As a patronymic surname, the surname Petrov was formed from a father's or ancestor's personal name — the single largest way hereditary surnames arose across Europe. Before family names became fixed, a man was often known as the son of his father (for example “John, son of Robert”), and over generations that link hardened into an inherited surname. Different cultures marked the relationship differently: English and Scandinavian names added “-son”, Irish and Scottish used “Mac” or “O’”, Slavic languages added “-ov”, “-ev” or “-vich”, and many languages simply reused the father's name unchanged. A patronymic surname therefore points back to a founding ancestor rather than a place or an occupation.

How Russian surnames work

Russian surnames are overwhelmingly patronymic in form, built with the possessive suffixes “-ov”/“-ev” and “-in” (“belonging to”), as in Ivanov (“Ivan's”) and Petrov. A distinctive feature is grammatical gender: a family's surname takes an “-a” ending for women (Ivanov / Ivanova). Some names are occupational (Kuznetsov, from “smith”) or descriptive, but the patronymic pattern dominates.
