About American last names

There is no single kind of American last name, and that is exactly what makes one sound American. The census top ten is already a mix: Smith, Johnson, Williams, Brown and Jones from England and Wales; Garcia, Rodriguez, Martinez and Hernandez from the Spanish-speaking world; Miller and Davis sitting in between. Go a little further down and you hit Nguyen, Patel, Kim, Murphy, Schmidt and Nakamura. A cast of characters whose surnames all came from one country will read as British or Irish, not American.

The list opens with the hundred most common surnames in the United States, then moves through names that signal a place or a community: Cajun French (Boudreaux, Thibodeaux, Fontenot), Pennsylvania Dutch (Stoltzfus, Yoder, Zook), old Dutch New York (Van Buren, Schuyler, Stuyvesant), Scandinavian Upper Midwest (Lindstrom, Gustafson, Halvorsen), Polish and Italian industrial cities (Kowalski, Esposito, DeLuca), Jewish (Goldberg, Shapiro), Irish (O'Connor, Gallagher), Appalachian (Hatfield, Sizemore, Caudill), surnames long carried by Black American families (Booker, Hairston, Pinckney), New Mexican Spanish (Archuleta, Trujillo, Baca), Navajo (Begay, Yazzie) and Asian-American (Tanaka, Choi, Shah, Huynh).

Every entry is a real surname in use today. For a small-town sheriff, reach for something regional; for a 1920s New York detective, an Irish or Jewish name fits the period; for a modern city, pull from anywhere on the list.

How to choose American last names

• Match the surname to where and when the story is set: Cajun names belong in Louisiana, Pennsylvania Dutch names in Lancaster County, Scandinavian names in Minnesota, and a Nguyen or Tran reads most naturally after 1975.
• Pair surname and first name era-appropriately. A Hatfield named Brayden and a Stoltzfus named Jaxon are possible but jarring; a Hatfield named Earl and a Stoltzfus named Amos land without effort.
• For a realistic group of characters, draw from at least three origins – an O'Neill, a Garza and a Lindstrom on the same softball team is more American than three Anglo names.
• Use a very common surname (Smith, Johnson, Brown) when you want a character to feel ordinary or anonymous, and a rarer regional one (Fontenot, Ravenscroft, Witherspoon) when the name should stick.
• Check spelling variants before you commit: Hanson and Hansen, Schultz and Schulz, Gonzalez and Gonzales are all real and each hints at a slightly different family history.

Frequently asked questions

What are the most common last names in America?

According to the U.S. Census Bureau, the ten most common surnames are Smith, Johnson, Williams, Brown, Jones, Garcia, Miller, Davis, Rodriguez and Martinez. Garcia, Rodriguez, Martinez and Hernandez all moved into the top fifteen in the 2010 census, and Nguyen is now in the top forty.

Are these real American surnames?

Yes. Every name in the list is a surname carried by families in the United States today, taken from census-common names and from well-documented regional and immigrant communities. None are invented, so they are safe for realistic fiction, screenplays, test data and character sheets.

What makes a last name sound distinctly American rather than English?

Usually its mix of origins and its spelling. Americanised German names like Eisenhower and Pfeiffer, anglicised Dutch names like Van Dyke, French Louisiana names like Boudreaux, and Hispanic names like Garza or Trevino all read as American to most ears. Even English-origin names can feel American through association, like Jefferson, Franklin or Washington.

Can I use these last names for characters in a published book or game?

Yes. Surnames are not protected by copyright or trademark on their own, so you can use any of them freely. The only caution is to avoid pairing a distinctive surname with a first name that produces the full name of a real, recognisable person.
