Most of us have mastered the rules for making common nouns plural (books, foxes, babies, valleys) and the many exceptions to those rules (men, women, children, people). Names, however, trip a lot of people up, despite having a simpler set of rules with no exceptions.

Most names can be made plural simply by adding an S:
The Smiths live next door. Their son, John, is one of three Johns in his class.

For names ending in CH, SH, S, X or Z, use “-es,” same as with common nouns:
The Bushes and the Cruzes are trying to keep up with the Joneses.
There are three Maxes and two Riches in our office.

Names ending in Y get an S, never an “-ies”:
The Kirbys, the Murphys and the Dickeys all named their daughters Becky. That’s a lot of Beckys!

Never, ever use an apostrophe – alone or with an S – to pluralize any noun that is more than one letter long.
