I ignore if we have ever search our first name following by our surname in Internet. If we have a common name, o not especially a common surname (like me), probably you will experiment a perturbing sensation testing that other person with the same name than you is living in the world. ¡¡Our identity can feels threatened!
In Spain there is a lot of names that refer to professions, like as Vaquero, Pescador, for example.
