My "hispanic" family name

[luis magistrado]

Hello. I am a Filipino. I have always believe that my family name is a spanish. When i was a kid when i learned that Magistrado means magistrate. My father also told me that his maternal great grand father was a spanish friar named Molinero who was assigned to the Philippines from Toledo, Spain. I don't know how our family name became Magistrado.

Now that I am learning spanish, i tried to search through the web for names of persons from Spain and its former colonies in with the family name Magistrado but I can not find any.

I would like to ask anybody here who is from a hispanic country, is the name Magistrado used as a family name?

Thank you.
