Piotrowski
Piotrowski (Polish pronunciation: ; feminine: Piotrowska, plural: Piotrowscy) is a Polish surname derived from the masculine given name "Piotr" (Peter). The name, and its variations indicate a family's origin as being from a town, such as for instance Piotrów and Piotrowo, or a toponym (place name) deriving from a holding, manor or estate. Variants and related names include "Piotrowicz", "Piotrowiak", "Piotrowsky", "Pietrowski", "Pietrkowski", "Pietrowsky", and "Pietrowiak". This surname is mainly found in Poland and Russia and the former territories of the Polish–Lithuanian Commonwealth. It is particularly widespread in Poland, where it is the 19th most common surname, with  61,844 bearers in 2009. Descendants of certain noble families, including that of a minor Tatar Knyaz that most likely had Naiman-Beg's youngest son, also bear the name or variations thereof. Comital and baronial branches exist as well. The earliest recorded usage of the surname can be traced back to the 11th century. Heraldry.
