SINGULAR POSSESSIVE: Mr. Smith's house, Ms. Jones's house
PLURAL POSSESSIVE: The Smiths' house, the Joneses' house
[as you would
pronounce it]
With names, an apostrophe is used only to show possession, never to show plurals. Here's a good way to remember how to spell possessive names:
First, decide if the name is singular or plural and spell it
correctly.
Next, add an apostrophe to the end of the word you've just spelled.
Finally, add another s only if you would ordinarily pronounce that extra
s when speaking the word. (Pronouncing that final s is a matter of style; choose the style that's most natural sounding to you, and be consistent in applying it.)
