when you hear the last name...?

Hispanic, at least. Most of the Hispanics know have Mexican ancestry. If I lived in Peru or Argentina or the Philippines, I would have a different outlook.

Mexicans are Latinos but not all people with the surname Reyes are Mexican. This is a Spanish surname so, yes anyone born with the surname Reyes would be Latino.

Origin: Spanish

Coat of Arms: A blue shield with a castle and a crown, and a red border with crosses.

Crest: Description not available

Spelling variations of this family name include: Reyes, Rey, de Reyes, de los Reyes, del Rey, Reina, de la Reina, de Reina, Reinoso, de Reinoso, Reynoso, de Reynoso, Reinosa, de Reinosa, Reynosa, de Reynosa, Real, de Real and many more.

First found in Castile, an important Christian kingdom of medieval Spain.

Some of the first settlers of this family name or some of its variants were: Among the early migrants to the New World were Esteban Real, who sailed to America in 1511; Diego Reales sailed to America in 1515; Bartolomé de Real sailed to America in 1516.

Not particularly, because it can also be several other ethnic groups. Latino is not an ethnic group the work represents more than "Mexicans" and is therefore really useless to use when describing an ethnicity.
