Here’s the deal. Don’t use an apostrophe to simply indicate a plural, whether the plural word is a common noun or a proper noun.
- Incorrect: I saw the Jones’ today
- Correct: I saw the Joneses today
When it comes to pronouns, we don’t use apostrophes—unless we’re making a contraction, smooshing two words together.

- Correct: Is that yours or hers?
- Incorrect: Its one of those dogs that has it’s tail between it’s legs
- Correct: It’s one of those dogs that has its tail between its legs
