Saiz
A Spanish surname most often understood as a regional form of Sáez, meaning “son of Sancho” or, more broadly, a patronymic from a medieval personal name.
The #6,888 most common surname in the United States (2010 Census) — about 1 in every 63,293 Americans shares it.
Etymology
Saiz is a Spanish surname usually treated as a regional spelling of Sáez, a patronymic formed from the old personal name Sancho. Sancho itself goes back to a Latin name, Sanctius, ultimately linked with the idea of “holy” or “consecrated.” In practice, surnames of this type identified someone as the descendant of a man named Sancho, rather than describing an occupation or place.
History
The surname is found chiefly in Spain and in Spanish-speaking communities in the Americas. Spellings such as Saiz, Sáiz, and Sáez reflect older regional and orthographic variation, especially in northern Spain. In modern usage, Saiz survives as a relatively uncommon but well-established Spanish surname.

Fun fact
Because Spanish surnames often preserve older local pronunciations, Saiz can look unrelated to Sáez even when they are historically connected.
