Dutra
A Portuguese surname, likely a regional or locational name connected to the Douro River or a place-name based on it.
The #7,838 most common surname in the United States (2010 Census) — about 1 in every 73,076 Americans shares it.
Etymology
Dutra is generally understood as a Portuguese surname tied to the old place-name Doutra or D’Outra, often explained as meaning "of the Douro" or "from the Douro region." In Portuguese surname formation, such forms commonly arose from a person’s place of origin rather than from a personal characteristic. The name may therefore reflect an ancestral association with the Douro valley or another locality built on the same root.
History
The surname is found in Portugal and in Portuguese-speaking communities, especially Brazil, where many Portuguese family names became widespread through colonization and migration. In modern usage it is most often treated as a hereditary family name rather than a transparent place indicator. The surname is also well represented among Brazilian families, which explains its visibility in the Americas.

Fun fact
Portuguese surnames beginning with apostrophized or reduced forms often preserve old prepositions like de or d’, even when the modern spelling looks compact and opaque.
