Niculescu

Niculescu is a common Romanian surname. The suffix '-escu' is a patronymic suffix, meaning 'son of' or 'descendant of'. It is one of the most common surname endings in Romania, indicating a direct lineage from a male ancestor. In this case, the ancestor's name would have been Nicolae.

The name Nicolae itself is the Romanian form of Nicholas, which derives from the Greek name Nikolaos (Νικόλαος), meaning 'victory of the people' (nikē 'victory' and laos 'people'). Therefore, Niculescu literally translates to 'son of Nicholas' or 'descendant of Nicholas'. Surnames ending in '-escu' became widespread in Wallachia and Moldavia, the principalities that formed modern Romania, particularly from the medieval period onwards.
