My last name is Meraz too. My grandparents were born in Mexico, but neither was Mexican by blood. Their parents (my great grandparents)were immigrants from Spain & France. So it's been my understanding that the name originated from Spain.
The name "Meraz" is a Spanish name and it comes from the name Asturian-Leonese Merás, which is a habitational name from Merás in Asturies. Please visit the following link in order to get more information about its origin.
