Juárez
A Spanish surname that began as a patronymic, historically linked to an older form of the name Suarez/Xuárez.
The #306 most common surname in the United States (2010 Census) — about 1 in every 3,028 Americans shares it.
Etymology
Juárez is a Spanish surname that originally functioned as a patronymic, meaning it identified someone as a descendant or family member of a man called Suero, in older spellings Xuárez. The source excerpt explicitly calls it an old patronymic form of Xuárez, which fits the broader history of Spanish surnames ending in -ez. The ultimate root of Suero is usually traced to a medieval personal name of uncertain origin, sometimes linked in older scholarship to Basque or Visigothic naming traditions.
History
The surname is well established in Spain and spread widely through the Spanish-speaking world during the colonial era. A famous bearer is Benito Juárez, the 19th-century Mexican president and national reformer, whose fame helped make the name especially familiar in Mexico and beyond. In modern usage the accent is often dropped in English-language contexts, but the Spanish form is Juárez.

Fun fact
Because Spanish spelling has changed over time, Juárez can be seen as preserving an older surname form that once appeared with X instead of modern J.
