Santillán
A Spanish surname most likely tied to a place-name built on a saint’s name, with the final form shaped by regional pronunciation and spelling.
The #2,756 most common surname in the United States (2010 Census) — about 1 in every 23,603 Americans shares it.
Etymology
Santillán is a Spanish surname most naturally explained as locational, from a place-name based on santo/santa, “saint,” plus a personal saint’s name. The excerpt groups it with forms like Santián, Santullán, and Santullano, which suggests a family of surnames created from saint-based place names or local pronunciations rather than a single transparent word root. The precise place behind the surname is not identified in the excerpt, so the literal meaning is best treated as “from the Santillán place-name,” rather than a fully secure dictionary derivation.
History
The surname is found in Spanish usage and later appears in Hispanic diaspora communities, including the United States. The excerpt reflects older orthographic variation in which the name could be written with or without the accent and with nearby regional spellings. Because the source only mentions the name incidentally, there is no solid evidence here for a single origin village or for an especially famous bearer.

Fun fact
