The Book Doctor sets it straight on apostrophe usage for writing on the road to publishing…
Q: When it comes to plurals for last names, which is correct? Hueys or Huey’s or Hueys’? The Robersons or Roberson’s or Robersons’? Microsoft Word always flags these as misspelled. I can never tell the difference.
A: Microsoft Word probably flags them because the words themselves, Hueys and Robersons, are not in the dictionary, plus the computer program cannot decipher whether the name is plural or possessive.
If it is strictly plural, it takes no apostrophe. Examples:
We ate dinner with Joe Huey and the rest of the Hueys.
Mike Roberson said all the Robersons are visiting next week.
If it is plural possessive, it needs an apostrophe. Examples:
We ate dinner at the Hueys’ house.
The Robersons’ dog is visiting, too.
Note that if the name ends in an s, the plural possessive for book style is to add an apostrophe and an s. Examples:
The Jones’s house is painted white.
I agree with all of the Samuels’s suggestions.
