What nationality is the name "Valderrago"

Question

I am a counselor at an outreach program at the Colburn school. Inner city public school elementary students who excel in arts and music attend the summer program for free. Out of 55 kids, 2 kids are Korean and the rest are Hispanic or African-American.

The students name is Samantha Valderrago. She speaks Spanish but she doesn't look Hispanic. Almost Native American looking but not quite. She's very pretty in an exotic way.

Answer 3

Where did you find this name?  There is no one in the census with this name that I could find.
