To show possession using an apostrophe, add ’s for individuals (“Smith’s car”) and just the apostrophe after the s for plurals (“the Smiths’ car,” “the Martinezes’ dog”). By convention, names from classical mythology and the Bible ending in s show possession with the apostrophe only (“Jesus’ teachings”).

Answer: To show singular possession, use the apostrophe and then the s. Example: I petted Mrs. Murphy’s cat. To show plural possession, always make the noun plural first, then use the apostrophe. Example: I petted the Murphys’ cat. Example: I visited the Murphys’ store on Main Street.

Apostrophes are used to show possession. For singular nouns and irregular plurals (those not ending in s), you should add ’s to the end of the word. For plural nouns ending in s, you should add only an apostrophe: the cat’s meow the people’s choice an old wives’ tale

The rules for using apostrophes with names are basically the same as those for all other nouns. Many rules are offered as a style guide for learning the English language for formal writing, including in the Chicago manual of style. For most names, you add an apostrophe and an “s” to make the possessive form.
