When it comes to writing last names in their plural form, clarity and correctness are key. Whether you’re referring to an entire family, multiple individuals sharing the same surname, or simply using last names as collective nouns, understanding the rules for pluralization helps maintain both grammatical precision and readability.
It might seem straightforward at first—just add an “s” or “es”—but as with many aspects of English, there are exceptions and nuances that deserve attention. Getting it right not only reflects well on your writing skills but also ensures your message is conveyed without confusion.
Many people struggle with last name plurals, especially when dealing with names ending in certain letters or when considering punctuation like apostrophes. Additionally, the plural form can sometimes intersect with possessives, which adds another layer of complexity.
If you’ve ever wondered whether to write “the Smiths” or “the Smith’s,” or how to pluralize a last name like “Jones” or “Harris,” you’re not alone. Let’s delve into the essential guidelines, examples, and exceptions to help you confidently write last names in the plural form.
Basic Rules for Pluralizing Last Names
The foundational rule for making most last names plural is quite simple: typically, you add an “s” at the end. This straightforward method works well for the majority of surnames that don’t end with special letters or sounds.
For example, if you want to refer to the entire family of someone named Johnson, you write “the Johnsons”. This indicates multiple people sharing the same last name without confusion.
However, understanding the basic rule is just the beginning. The English language has specific conventions when it comes to names ending in certain letters like s, x, z, ch, or sh.
These require a slightly different approach.
How to Apply the Basic Rule
- Add “s” to most last names: the Browns, the Miller’s (note: possessive forms differ)
- Do not use an apostrophe for plurals; apostrophes indicate possession
- Capitalize the last name as it’s a proper noun, regardless of pluralization
“Adding just an ‘s’ often suffices for plural last names, but always watch out for exceptions that require ‘es’.”
Pluralizing Last Names Ending in S, X, Z, CH, or SH
Last names that end with sibilant sounds like S, X, Z, CH, or SH typically require an “es” ending to form the plural. This helps maintain the smooth pronunciation of the word.
For instance, if you’re referring to the entire Jones family, you would write “the Joneses”. Similarly, a family named Harris becomes “the Harrises”.
Adding “es” in these cases prevents awkward or unclear pronunciation that would occur if you simply added “s.” This rule is consistent and important to remember.
Common Examples
| Singular Last Name | Plural Form |
| Jones | Joneses |
| Fox | Foxes |
| Church | Churches |
| Bush | Bushes |
- Do not add only “s” to these names (e.g., Joness is incorrect)
- Remember that apostrophes are not used for plurals, only possessions
When Not to Use Apostrophes in Plural Last Names
One of the most common errors is confusing plurals with possessives. Apostrophes are used to indicate possession or contractions, not to form plurals.
This is a key distinction when writing last names in plural form.
For example, when writing about the entire Smith family, the correct form is “the Smiths”, not “the Smith’s”. The latter implies possession, as in “the Smith’s house” (referring to something belonging to the Smith).
Using apostrophes incorrectly can distract readers and make writing appear less professional. It’s a simple rule but one that requires attention to avoid common pitfalls.
Examples of Common Mistakes
- Incorrect: The Johnson’s are coming over.
- Correct: The Johnsons are coming over.
- Incorrect: The Harris’ car is new. (unless showing possession)
- Correct: The Harrises are here.
“Apostrophes belong to possessives, not plurals. Keeping this straight is crucial for clear writing.”
Pluralizing Last Names Ending with Y
Last names ending in Y can be tricky, but the key is to look at the letter preceding the “Y.” If the letter before the “Y” is a consonant, you usually change the “Y” to “ies”. If it’s a vowel, you simply add an “s”.
For example, the last name Murphy ends with a consonant before the “Y,” so it becomes “the Murphies” when pluralized. However, for a name like Bailey, which has a vowel before the “Y,” the plural is “the Baileys”.
This rule aligns with general English pluralization for common nouns, making it easier to remember.
Examples and Exceptions
| Last Name | Plural Form |
| Murphy | Murphies |
| Bailey | Baileys |
| Kenny | Kennys |
- Change “y” to “ies” if a consonant comes before the “y”
- Add just “s” if a vowel precedes the “y”
- Always keep the capitalization consistent
Plural Last Names with Prefixes and Compound Names
Last names with prefixes like Mc, Mac, or O’, as well as compound last names, have specific pluralization conventions. These names require that you pluralize the main surname part rather than the prefix.
For example, the plural of McDonald is “the McDonalds”, not “the McDonald’s.” For compound names like Smith-Jones, the plural form is “the Smith-Joneses”.
Understanding how to handle these particular names ensures your writing remains polished and grammatically accurate.
Handling Prefixes and Compound Names
- Pluralize the main last name, leaving prefixes unchanged: the O’Neills
- For hyphenated names, pluralize the last element: the Carter-Williamses
- No apostrophes are used unless indicating possession
“Compound last names take the plural form of the final part, making ‘the Smith-Joneses’ correct and clear.”
Using Last Name Plurals in Different Contexts
How you pluralize a last name can depend on the context. For example, in casual conversation, printed invitations, or formal writing, the conventions might subtly shift.
However, the fundamental rules remain consistent.
In invitations, you often see last names pluralized to refer to families, such as “the Andersons.” In academic or professional writing, plural last names may appear when discussing groups or generations.
It’s important to apply pluralization rules consistently, but also adapt your style to the tone and purpose of your writing.
Examples Across Contexts
- Invitations: The Garcias request the pleasure of your company.
- Academic writing: The Parkers conducted a study on urban growth.
- Casual speech: We went to the Williamses’ house for dinner. (possession)

Special Cases and Irregular Plurals
Some last names do not follow the general rules and require special consideration. For example, names ending in “man” or foreign names with unique plural forms may deviate from standard English pluralization.
Names like Hoffman become “the Hoffmans”, but some names borrowed from other languages might retain their original plural forms. It’s always a good idea to research or ask if you’re unsure about a specific last name.
These irregularities highlight the rich diversity of surnames and the importance of context and respect for cultural naming conventions.
Examples of Irregular and Foreign Plurals
- Germanic names: Hoffman → Hoffmans
- Latin-based names: Some may remain unchanged or add “i” (e.g., Ferrari → Ferraris)
- Names with non-English origins: Often best to follow the family’s preferred usage
“When in doubt, consult family preferences or trusted style guides to respect name origins and plural forms.”
Common Mistakes to Avoid
Writing last names in the plural form is deceptively tricky, and it’s easy to fall into common pitfalls. One frequent error is mixing up plurals with possessives, which can change the meaning of your sentence entirely.
Another mistake involves incorrect endings—such as adding “es” unnecessarily or failing to add it when needed—which can distract readers and undermine your credibility.
Proofreading and understanding these common mistakes go a long way in polishing your writing and ensuring your message is clear.
Typical Errors and Corrections
| Mistake | Correction |
| The Davis’ are here. | The Davises are here. |
| The Foxs went to the park. | The Foxes went to the park. |
| The Murphy’s house is big. | The Murphys’ house is big. (possession) |
- Remember: plurals do not include apostrophes
- Use “es” endings for last names ending with sibilant sounds
- Check carefully for names with tricky endings like “y”
