Why do most spanish last names end in this?!? only answer if youre mexican or if you study mexican heritage!?

Question

i was wondering my most spanish last names or a lot of them anyways end in ez. some examples are: velasquez, rodriguez, lopez, martinez, torrez, Diaz, perez, mendez, Hernandez, Ramirez, González, etc... its an easy ten points ONLY if youre mexican or you know a lot about mexican history and you give a DETAILED answer.

Answer 1

The reason originated from sons and daughters taking their father's first name and adding common endings like -ez, -az, -is, or -oz (common to Castilian or Spanish surnames). These are called Patronymic Surnames. It was used as a sign of respect. An example of this is:

Leon Alvarez (Leon Son of Alvaro).

Answer 2

Agree with answerer number 1 that it means son of Gonzalo or Rodrigo, etc... You don't have to know about Mexican culture to know this answer.  This is rooted from Spain and old Spanish language perhaps from the time of Cervantes or before.  

Answer 3

i love the people that tell you not to answer their question unless you meet their specifications. I am white, but have spanish family members. Is that good enough for you? Do i qualify to answer your question. And the humor is no matter what you think, say or feel my words will be here simply taking up space in your face. In a nut shell i assume you have alot on common with the worst examples of smart people. an easy 10 points that don't matter any more than the value the holder puts upon them.  

Answer 4

Those are patronymic surnames similar to Johnson, Peterson, Jacobson, etc.  They were originally based on a parent’s given name, usually the father.

Juan Alvarez = Juan, son of Alvaro.
