Shortest last names
The 2000 USA census contains no surnames with ONE character.
The shortest last names there have at least two characters in them. We found 175 of those. It does not mean that a one
character name does not exist. The census data only contain surnames that occurred at least 100 times
at the time the survey took place. I am sure not all the two character surnames that exist in the United States
are on the list below either for the same reason.
Please, let us know if your surname is a 2 character surname and is not here. Please, be certain to communicate if
your surname is a one character surname!
