You’ve got a stack of envelopes ready, a pen in hand, and then you pause. The family you’re writing to is the Williamses. Maybe you’ve seen both versions and now you’re second‑guessing which one looks right. Or is it the Williams’? It’s a tiny detail, but it feels like it could make the whole card look sloppy if you get it wrong.
What Is a Last Name That Ends in S
When we talk about a “last name that ends in s,” we mean any surname whose spelling finishes with the letter s—think Jones, Harris, Brooks, or even something less common like Yeats. On top of that, the question isn’t about the name itself; it’s about how to make that name plural when you’re referring to more than one person who shares it, or when you want to show possession. In everyday writing, you’ll run into this when you’re addressing holiday cards, signing a group email, or noting a family’s ownership of a house.
Why the Plural Form Matters
The plural form tells readers you’re talking about multiple individuals, not just one. That can cause confusion, especially in formal contexts like legal documents, invitations, or academic citations. If you write “the Jones” when you mean the whole Jones family, you might accidentally suggest you’re only talking about a single person named Jones. Getting it right shows attention to detail and respect for the people you’re writing about.
How the Rules Actually Work
Most style guides agree on a simple pattern: add es to the end of the surname. So Jones becomes Joneses, Harris becomes Harrises, Brooks becomes Brookses. The added es makes the pronunciation clear—you’ll say “Jones‑ez” rather than trying to squeeze an extra s sound into a single syllable.
When the Name Already Ends in a Soft Sound
Some names that end in s are pronounced with a soft “z” sound, like “Yeats” (which sounds like “Yeets”). Practically speaking, even there, the plural is formed by adding es: Yeatses. Consider this: you’ll still say “Yeats‑ez. ” The spelling might look a little odd at first, but it follows the same logic as words like “glass” → “glasses” or “class” → “classes.
Possessive Forms – A Quick Side Note
If you need to show that something belongs to the plural family, you first make the plural, then add an apostrophe after the final s. For example: the Joneses’ house, the Harrises’ car. So the Williamses. If you’re only talking about one person named Jones and want to show possession, you’d write Jones’s (or Jones’ depending on the style guide you follow). But for our focus—plural family names—remember: plural first, apostrophe after.
Why It Matters / Why People Care
Getting the plural right isn’t just about grammar nitpicking. ” Guests might wonder if you’ve forgotten to include a spouse or children. Imagine sending a wedding invitation that addresses “the Smith” instead of “the Smiths.It affects how your message is received. Day to day, in a business setting, addressing an email to “the Patel” when you mean the whole Patel team could make you look careless. Even in casual texts, a mistaken plural can lead to a quick follow‑up clarification that interrupts the flow of conversation.
Real‑World Examples
- Holiday cards: You want to write “Season’s Greetings from the Garcias!” If you accidentally write “Garcia,” the card reads as if only one person named Garcia is sending greetings.
- News articles: A reporter covering a lawsuit might need to mention “the Nguyens’ claim.” If they write “Nguyen’s claim,” readers could think only a single Nguyen is involved.
- Academic citations: When referencing a study by multiple authors with the same last name, you’ll see “Lee et al.” in the text, but the bibliography might list “Lees, J. & Lees, M.” (hypothetical example). Knowing the plural form helps you interpret those entries correctly.
How It Works (or How to Do It)
Let’s break down the process into clear steps you can follow whenever you need to pluralize a surname that ends in s.
Step 1: Identify the Base Name
Make sure you’re working with the actual surname, not a title or a nickname. Because of that, for example, if you’re dealing with “De La Cruz,” the part that ends in s is “Cruz. ” You’d pluralize “Cruz” to “Cruzes,” then reattach the prefix: “De La Cruzes.” (In practice, many style guides keep the prefix unchanged and just pluralize the final element.
Step 2: Add es to the End
Take the base name and tack on es. No need to drop the original s; just append the two letters. This works for virtually every surname that ends in s, regardless of how it’s pronounced.
- Davis → Davises
- Andrews → Andrewses
- Flores → Floreses
Step 3: Check Pronunciation (Optional but Helpful)
Say the new form out loud. If it feels clunky, you’re probably doing it right—the added es creates a distinct syllable that makes the plural clear. If you accidentally drop the e and just add an s (Daviss), it sounds like a possessive or a weird singular form, which is why the extra e matters.

Step 4: Apply Apostrophe for Possession (If Needed)
If you need to show ownership, place the apostrophe after the newly formed plural.
- The Levines’ vacation home (plural Levine → Levines, then apostrophe)
- The Rosses’ backyard (Ross → Rosses, then apostrophe)

Step 5: Avoid the Common "Apostrophe Trap"
The most frequent error occurs when people mistake pluralization for possession. Plus, , writing "The Smith's are coming over"). So g. That's why a common mistake is adding an apostrophe simply to make a name plural (e. This is grammatically incorrect.
Remember:
- Plural only: Add s or es (The Smiths).
- Singular possessive: Add 's (John Smith's car).
- Plural possessive: Add s and then the apostrophe (The Smiths' car).
If you aren't trying to show that something belongs to the family, keep that apostrophe far away from the end of the name.
Summary Checklist
Before you hit "send" on that important email or sign off on a formal invitation, run through this quick mental checklist:
- Is it a plural or a possessive? (If you aren't showing ownership, there should be no apostrophe.)
- Does the name end in S, X, Z, Ch, or Sh? (If so, add es.)
- Did I add an extra "s" to the base name? (If the name is "Jones," the plural is "Joneses," not "Joneses's.")
