Do you know the correct methods for Pluralizing Last Names?
Making the plural form of a proper name can be challenge without this information. Use it to be spot-on, and be able to handle someone else’s name with the greatest of respect (by getting its plural form correct!).
| Last letter(s) of last name | What to add to make it plural? | Does it need an apostrophe? | |
| a, b, c, d, e, f, g, h (see exceptions below), i, j, k, l, m, n, o, p, q, r, t, u, v, w, y | -s | NO | |
| s, x, z, ch, sh | -es | NO |
Chart from Kate Brannon of Slate.com
For last names that end in –y, add “s.” Do not add “ies” or an apostrophe.
Example: The Cantys will join us for dinner.
For last names that end in –s, add “es.” Do not add an apostrophe.
Example: The Atkinses went on vacation
For last names that end with what may seem like irregular nouns, they are not treated like irregular nouns when they are part of a last name.
Example: The Glickmans had dinner with the Wolfs (NOT the Glickmen and the Wolves).
Apostrophes are NOT used to make last names plural, but can be used to make them possessive.
- The Goodwins’ house was used in a movie. [Plural Possessive]
- Rayna Hennen’s Company provides excellent service. [Possessive]
- The Filorimos wish you a Happy New Year. [Plural]
- Let’s go visit the Hertzes. [Plural]
While pluralizing last names can be a tricky task – make sure your holiday cards and correspondence are all handled correctly!
