For some reason this has me confused, maybe its my 6th grade education but I have a customer that needs some text printed on the back of some shirts and a question on apostrophe has come up. What is correct?

GRANDPARENT'S CREW
GRANDPARENTS' CREW
GRANDPARENTS CREW

ROBERT'S CREW
ROBERTS' CREW
ROBERTS CREW

Depends on the context...

If they are a crew of grandparents, then it is Grandparents Crew.  If the last name of the person they are cheering on is Robert, it would be Robert's Crew.

[im_mcguire]

if its possessive as the Grandparent owns the crew it would be Grandparent's Crew.

[Prosperi-Tees]

Thanks guys, it just was not computing in the old noggin.

[mimosatexas]

's means one subject has ownership (grandparent's crew means ONE grandparent (either grandpa OR grandma) "owns" the crew)
s' means multiple subjects have shared ownership (grandparents' crew means MULTIPLE grandparents (grandpa AND grandma) "own" the crew)
no apostrophe just implies multiple grandparents are in the crew, but there is no ownership implied.

  Or in the case of Roberts, If the person's name is Robert it would be Robert's crew. If
the name is Roberts then it would be Roberts' crew

[Prosperi-Tees]

Is this part of the reason why some say English is the hardest to learn?

[Stinkhorn Press]

's means one subject has ownership (grandparent's crew means ONE grandparent (either grandpa OR grandma) "owns" the crew)
s' means multiple subjects have shared ownership (grandparents' crew means MULTIPLE grandparents (grandpa AND grandma) "own" the crew)
no apostrophe just implies multiple grandparents are in the crew, but there is no ownership implied.

me still struggle with this. sigh.
contractions, i got. singular and plural possessive, it's a guess everytime.

For some reason this has me confused, maybe its my 6th grade education but I have a customer that needs some text printed on the back of some shirts and a question on apostrophe has come up. What is correct?

GRANDPARENT'S CREW   (one grandparent has a crew, singular possessive)
GRANDPARENTS' CREW   (both grandparents have a crew, plural possessive )
GRANDPARENTS CREW    (a crew made up of grandparents)

ROBERT'S CREW    (one person named Robert has a crew, singular possessive)
ROBERTS' CREW    (the Roberts family or a group of people whose first name is Robert have a crew, plural possessive)
ROBERTS CREW     (a group of people whose first name is Robert make up the crew)

contractions are another discussion altogether...

[mimosatexas]

  Or in the case of Roberts, If the person's name is Robert it would be Robert's crew. If
the name is Roberts then it would be Roberts' crew

That is kind of true.  It is actually proper to do either Roberts' or Roberts's if it is a single subject.  The latter would clarify if it is one vs many, though it would sound strange to say it.

What are youse guys talkin' about? It's America, just stick that apostrophe wherever the hell you want! Or leave it off! Damn grammatical correctness!

[bimmridder]

Your right Andy. Nobody cares where you place you're apostrophe. You could put it at the beginning and yore the only one that will notice.

[Printficient]

Their is no mistaking that there apostrophes should be they're.

[Sbrem]

Their is no mistaking that there apostrophes should be they're.

I had a customer a few years ago with a school bus service "Transporting Americas' Students". I explained  the problem and he kind of poo poo'd me, until I told him to ask his wife when he got home. She straightened him right out, LOL
