The origins of my name!

The name Martina is the feminine form of the name Martin, originally Martinus.
Martina and Martin mean "dedicated to Mars", referring to the Roman god of war;  in fact the meaning of the name Martina is also "Servant of Mars".
Martina may also appear as a surname. In these cases, it is Italian or Czech in origin and derives from the male name Martin, perhaps as a patronymic that means "daughter of Marzio".
