Getting plural last names right is one of those small details that separates careful writing from careless writing. The rule itself is simple — to make a surname plural, you usually just add “s” or “es,” and you never add an apostrophe — but the exceptions for names ending in s, x, z, ch, and sh trip up almost everyone. This guide explains plural last names clearly, with examples for every ending, so you can address envelopes, write invitations, and refer to families with total confidence.
The confusion is understandable. English possessives use apostrophes, and most people learn “add ‘s” long before they learn the plural rule for names. The result is the classic error on holiday cards: “The Smith’s” when the writer means “The Smiths.” Once you separate the two jobs — plurals name more than one person, possessives show ownership — the whole topic becomes straightforward.
Plural Last Names: The Basic Rule
The basic rule for plural last names is: add “s” to the end of the name, with no apostrophe. The Smith family becomes the Smiths. The Johnson family becomes the Johnsons. The Patel family becomes the Patels. The Garcia family becomes the Garcias. That is all there is to it for the majority of surnames — names that end in a vowel or in most consonants simply take an “s.”
The no-apostrophe rule is the single most important point in this guide. An apostrophe signals possession or a contraction, never a plural. “The Smiths are coming for dinner” is correct; “The Smith’s are coming for dinner” is not, because the apostrophe turns the family name into a possessive with nothing to possess. If you remember nothing else from this article, remember this: plural last names never take an apostrophe.
Here are everyday examples of the basic rule in action:
- “We spent the weekend with the Browns.”
- “The Patels moved into the house next door.”
- “Please welcome the Johnsons to the neighbourhood.”
- “The Garcias host the street party every summer.”
Note how natural these look once the apostrophe habit is broken. If you are writing about families from other cultures, the same rule applies: add “s” and stop.

Plural Last Names Ending in S, X, Z, Ch, and Sh
Names ending in s, x, z, ch, or sh follow a different pattern: add “es” instead of “s.” The Jones family becomes the Joneses. The Fox family becomes the Foxes. The Marsh family becomes the Marshes. The Church family becomes the Churches. The reason is pronunciation: adding a bare “s” to these endings would be unpronounceable, so English inserts a vowel sound, spelled “es,” to make the plural sayable.
This rule covers a large group of common surnames, and it is where most errors happen. People write “the Jones’s” or “the Jones'” when they mean “the Joneses,” or they add a plain “s” and produce the awkward “Joness.” The fix is mechanical: check the final letter or letters of the name, and if they are s, x, z, ch, or sh, add “es.” The table below covers the main cases:
| Name ending | Singular | Plural | Pronunciation |
|---|---|---|---|
| Most letters | Smith | Smiths | smiths |
| s | Jones | Joneses | john-ziz |
| x | Fox | Foxes | fox-iz |
| z | Gomez | Gomezes | goh-mez-iz |
| ch | Church | Churches | church-iz |
| sh | Marsh | Marshes | marsh-iz |
Names ending in a silent “s” or with unusual spellings still follow the same logic: pronounce the plural aloud, and if you hear an extra syllable, spell it with “es.” When in doubt, saying the name out loud is the most reliable test in English grammar.
Plural Last Names and Possessives Combined
Things get trickier when a plural surname also needs to show possession — for example, the house belonging to the Jones family. The correct order is: make the name plural first, then add the possessive marker. For names ending in “s” after pluralisation, that means adding only an apostrophe: “the Joneses’ house,” “the Foxes’ garden,” “the Smiths’ car.” For plural names that do not end in “s” — which is rare, since most plural surnames do end in “s” — you would add “‘s,” but in practice nearly every plural possessive surname ends with “s” plus an apostrophe.
Walk through the steps with the Jones family: singular Jones, plural Joneses, plural possessive Joneses’. With the Smith family: singular Smith, plural Smiths, plural possessive Smiths’. The logic never changes: plural first, possessive second. Writers who reverse the order produce errors like “the Jones’s house” when they mean the whole family’s house, or “the Jone’s house” when they mean one person named Jone. Slow down, apply the two steps in order, and the result is always correct.
This same care matters when writing about naming customs in different cultures. In some traditions, family names work differently — for instance, our article on whether Chinese women take their husband’s last name explains a system where the whole question of plural and married names follows different conventions.
Plural Last Names on Invitations and Envelopes
Invitations and envelopes are where plural last names cause the most public embarrassment, because the error is printed and displayed. The rule for addressing a family is the same as everywhere else: use the plural form with no apostrophe. “The Smiths” on an envelope is correct. “The Smith’s” is not, and “The Smiths'” with a trailing apostrophe is only correct if the envelope itself implies possession, which it does not.
A few practical tips help. First, never guess at a plural for an unfamiliar name — check the spelling with the family if you can, especially for names ending in silent letters or with non-English origins. Second, for hyphenated surnames, pluralise only the final element: the Smith-Jones family becomes the Smith-Joneses. Third, for two unmarried partners with different surnames, list both names in full (“Ms Patel and Mr Okafor”) rather than forcing a combined plural. Fourth, on formal invitations, use titles with the plural (“Mr and Mrs Smith”) only when you are certain of the couple’s preference; “The Smiths” is the safer, modern default.
Holiday cards deserve a special warning, because the festive season produces more apostrophe errors than any other occasion. Card companies even sell pre-printed cards reading “The Smith’s,” which has normalised the mistake. If you receive such a card, smile and enjoy it; if you are sending one, take the extra second to check that your family name ends in “s” or “es” with no apostrophe in sight. The same discipline applies to email signatures, social media bios, and return-address labels — anywhere plural last names appear in print, the no-apostrophe rule holds, and a quick read-through before printing saves the embarrassment of a hundred misprinted cards.
Tricky Cases for Plural Last Names
A few surnames resist the standard rules. Names ending in “y” do not change the “y” to “ies” the way common nouns do: the Berry family becomes the Berrys, not the Berries, because surnames keep their spelling. The same applies to Murphy: the Murphy family becomes the Murphys, not the Murphies. Surnames are proper nouns, and proper nouns resist the spelling changes that common nouns accept.
Names of non-English origin sometimes have their own plural traditions, and the respectful approach is to follow the family’s own usage. Some families with Italian surnames ending in “o” or “i” prefer an “s” plural (“the Rossos”), while others keep the name unchanged in the plural. When a family’s preference is known, it overrides the general rule — grammar serves people, not the other way round.

Frequently Asked Questions
Do plural last names take an apostrophe?
No. Plural last names never take an apostrophe. “The Smiths” is correct; “The Smith’s” is a possessive, not a plural.
How do you pluralise a last name ending in s?
Add “es”: Jones becomes Joneses, Williams becomes Williamses. The extra syllable makes the plural pronounceable.
What is the plural possessive of a last name?
Make the name plural first, then add an apostrophe: the Joneses’ house, the Smiths’ car. The apostrophe goes after the plural “s.”
Do names ending in y change to ies?
No. Surnames keep their spelling: Berry becomes Berrys, Murphy becomes Murphys. The “y” to “ies” rule applies to common nouns, not proper names.
Conclusion
Plural last names follow a short, reliable set of rules: add “s” to most names, add “es” to names ending in s, x, z, ch, or sh, and never use an apostrophe for a plural. Possessives come second — plural first, then the apostrophe — and surnames keep their spelling where common nouns would change. With those principles in hand, you can write “the Joneses,” “the Smiths,” and “the Foxes” without hesitation, address envelopes correctly, and avoid the stray apostrophe that gives away an otherwise polished piece of writing.
