Possessive case
To talk about possession, we use the following:

• 's — after a singular noun: Bob's sister, my mother's car;

• 's or ' — after a singular noun ending in -s: Boris's/Boris' dog, the princess's/princess' father;

• ' — after a regular plural noun (ending in -s): the students' books, my friends' names;

• 's — after an irregular plural noun: the children's pens, the men's guitars;

• of (not 's) — for things and places: the capital of Russia, the windows of the house.

  In a "noun + noun" phrase we use 's only after the last noun:

This is Joanna and Peter's house. This is their house.

Alex is Tom, Anna and Mary's father. Alex is their father.

• My grandparents' names are John and Mary.
• John and Mary's children are Jane and Peter.
• His wife's name is Rose.
• Their children's names are Tim and Kate.
• My father's name is Tom and my brother's name is Ron.

The possessive case is used to say

• whose object it is
• what it is
• who it is

With singular nouns (e.g. wife, father, brother) we

• add '
• add 's
• add s'

With plural nouns (e.g. grandparents) we

• add '
• add 's
• add s'

With irregular forms of nouns (e.g. children) we

• add '
• add 's
• add s'

Which is correct?

• Tom's and Jane's daughter
• Tom's and Jane daughter
