Last Name Santos-dantas

What is the origin of the last name Santos-dantas?

The surname Santos-Dantas is a Portuguese-Brazilian name with origins rooted in both Portugal and Brazil. The name "Santos" is derived from the Portuguese word for saint (santo), which was often given as a religious name to children born during religious festivals dedicated to various saints. The surname Dantas, on the other hand, may have originated from the medieval village of Danta do Sul in Portugal, though its exact origins are unclear and it may also have been a nickname derived from the Latin word for tooth (dens or dentis). When Portuguese explorers and colonizers settled in Brazil, many brought their surnames with them. As the population grew over time, some families adapted their names to reflect their mixed heritage or regional variations. The name Santos-Dantas may have been formed by combining the two surnames at some point during this period of history.
