It is a very common last name; Spanish I think, but not positive. You'll find out if you Google it. Nice one to have. You might check to see if any of the country code extensions relevant to this name are still available...
Sorry, I don't know enough about the last-name domain names, especially with the dot.info, and also with foreign names, to appraise a value... but I'd hazard an ignorant guess that it's got to be at least into the med xxx, since there are many historical and contemporary figures with this last name so should be strong for an info site on them, or to sell to one of them...
