Domingo
Meaning
of the Lord; born on Sunday
The story
Domingo wears its calendar on its face. It is the Spanish word for Sunday, and Behind the Name traces the given name through Late Latin Dominicus, meaning of the Lord, a name traditionally given to a child born on that day. The tradition produced several saints, among them the thirteenth-century founder of the Dominican friars, and left the surname Dominguez behind it. In the United States the name has simply never gone missing: boys named Domingo appear in the Social Security record in thirteen straight decades, from the 1900s through the 2020s so far. Brazil's census tells the same story a generation older, counting 9,319 bearers with a median age of 59. The meaning sits right on the surface, no digging required, and whether or not the birthday actually lands on a Sunday, the name keeps the old custom within reach of the crib.
