Orosco

The #4,273 most common surname in the United States (2010 Census) — about 1 in every 37,140 Americans shares it.
Etymology
Orosco is generally understood as a Spanish surname from a place name, and many such names in northern Spain were built from older Basque or pre-Roman elements. It is often connected with a landscape term referring to a hill, ridge, or wooded place, though the exact original sense is not always certain. In surname use, it would originally have meant someone from or associated with such a place.
History
The name is found in Spanish-speaking regions and later spread widely through the Spanish colonial world and the Americas. In modern usage it is especially encountered in Mexico and among families of Hispanic heritage in the United States. Spellings with -sco and related forms reflect regional and historical variation in how the place name was written.
