Vicente Fox has a paternal ancestry direct from Germany. His Gt. Grandfather was Louis Michel Fuchs, his wife was Catherina formerly Flach. Both came as immigrants to Cincinnati, Ohio. He was an accomplished maker of items in the livery trade. He opened up a business in Mexico City, in 1897.
The name of Fuchs was changed to Fox. The Grandparents of this gentleman Vicente Fox were born in the USA. I would not think much of his chances of being where he is without this lineage.
The family name should have been changed to Zorro to make it authentically Spanish.
