Pétronille is the French form of Petronilla, a Latin name that gave rise to various European variants. The name ultimately traces back to the Roman family name Petronius, which may derive from Latin petro, petronis meaning "yokel" or "rustic." Despite its humble etymology, the name gained Christian currency through a legendary association with a 1st-century Roman saint. Early tradition identified Petronilla as a martyr and, from the 4th century onward, as an apocryphal daughter of Saint Peter, a claim reinforced by her name's similarity to the apostle's (from Greek petros, "rock"). This alleged filiation, though unsupported by historical evidence, elevated the name's status in Western Christianity.
In French, Pétronille emerged as a localized adaptation of medieval Latin Petronella, itself a diminutive of the feminine Petronia. While never overwhelmingly common in France, the name maintained a quiet presence into the modern era. Its forms in other languages include Pernille (Norwegian), Petronella (Swedish), Pietronella and Nel (Dutch), and Parnel (English). The English variant, Parnel, was relatively common in medieval England but declined after the Protestant Reformation, partially due to its associations with Catholicism.
Notable bearers of the French form include Pétronille de Chémilly (13th century), a French noblewoman, and, more famously, the pseudo-saint Petronilla, whose feast day is May 31. However, Pétronille remains a rare given name today, more often recognized through literature and historical records than in contemporary usage.
