Gasca
A surname of likely Iberian origin, probably tied to a place-name or regional label in Spain.
The #6,913 most common surname in the United States (2010 Census) — about 1 in every 63,606 Americans shares it.
Etymology
Gasca is most likely a Spanish surname that began as a locational or regional name. In Iberian naming, such surnames often came from a village, estate, or an identifying place association, though the exact source of this form is not certain. It may also reflect Basque influence in northern Spain, where many surnames developed from local topography and settlement names.
History
The surname is found in Spanish-speaking areas and later in the Americas through migration from the Iberian Peninsula. Because Gasca is relatively uncommon, it often appears in family lines with roots in Spain or in Spanish colonial and post-colonial migration streams. A notable historical bearer was Pedro de la Gasca, a 16th-century Spanish clergyman and royal official in Peru.
