Radwaniec

Radwaniec is a Polish surname. It is derived from the given name Radwan, which itself is of uncertain origin, potentially related to the Old Polish word "rad" meaning "glad" or "willing." The "-iec" suffix is a common Polish patronymic or occupational suffix, often indicating "son of" or "descendant of" (in the case of a given name) or someone associated with a particular profession. Therefore, Radwaniec likely originally denoted "son of Radwan" or "descendant of Radwan." The surname is relatively uncommon.
