Nemanja

Nemanja (Cyrillic: Немања) is a masculine Serbian given name. It is derived from the by-name borne by the founder of the Nemanjić dynasty, Stefan Nemanja (1114–1199), a Serbian grand prince who was venerated as a saint after his death.
Etymologically, many think the name most likely derives from a meaning "without possessions", from Serbian nemati "to have not", but that is not true. The name origins from ne manuti "not to let go" in terms of being persistent and stubborn.
