Williams’s or Williamses’?

When showing possession for a name like Williams, people often get confused. If you’re talking about one person, say Mr. Williams, you add an apostrophe and s—Williams’s car. But if you’re referring to a family with the last name Williams, you first make it plural—

Williamses—then add just an apostrophe for possession: the Williamses’ house. It may look strange, but it’s grammatically correct. Always think about whether it’s singular or plural before adding the possessive form.
