Pierson

Etymology

Pierson is a patronymic surname built from the medieval personal name Piers, meaning “son of Piers.” Piers was a common English form of Peter, ultimately from Greek Petros, “rock,” passed through Latin and Old French. In that sense, Pierson is closely related to Pearson and other Peter-derived surnames.

History

The surname is recorded in English sources as a straightforward family-name formation from a father’s given name. Nineteenth-century surname writers consistently treated Pierson as equivalent to Pearson in origin, though the exact spelling could vary by region and family line. It has also spread into other English-speaking countries and appears in Scandinavian-looking parallel forms such as Persson and Pierson, but those are not necessarily the same family in every case.

Fun fact
