Where does the name Martinez come from?

Answer 1

It is a Spanish surname meaning "son of Martin". So Mr Martinez had an ancestor whose first name was Martin.

"Martin" is a diminutive of "Marcus". "Marcus" means "belonging to Mars", who is the Roman God of War. The literal meaning of "Mars" is something like "the masculine principle".

So you can think of "Martinez" as meaning a warlike, masculine family.
