Follow the same rule when a name or a singular noun ends in -s. Write an apostrophe first and then add another s.
Examples :
-

-

For plural nouns that end in -s, put the apostrophe after the -s.

-
The bookstore sells newspapers, comics and women’s magazines.

You can also refer to a person’s office or shop by using a possessive form with an apostrophe.
Examples :
-

-

-

You can also refer to your friends’ homes in the same way.
Examples :
-

-

How do you make a possessive form of two people joined by and, such as Peter and John or Mary and Anne? Put ’s only after the second name.
Examples :
-
Barbara and David’s house
-
Jill and Andy’s party
These possessive forms of names and nouns can be used without a following noun.
Examples :
-

-
George’s is in the back row.
-

The apostrophe can also be used to show that one or more letters in a contraction have been left out.

-
