I thought it was Quite obvious as to who was the link

@dsagent  
Literally or not depends on head canon.

Everyone is Celestia’s children.

There is also the greeting.
 
Pinkie pie: “Ahhh yourself” beginning of the episode  
Goldie delicious: “Hello yourself”

I guess Pinnkie IS related to the Apple family.

Hereditary mad Jenga skills, could be. Gingerbread houses? Not so much.

All in all, it’s still ambiguous. Perhaps Goldie Delicious herself was simply a zany, Pinkie-like Apple in her youth. She’s certainly eccentric.
 
Dunno. Maybe this’ll tie in later.

Subtle hints right there, everypony!

na, the apples are related to everypony. they are a big family.

@Hellfire  
Pinkie Pie said she was a fourth cousin twice removed by a fifth cousin. That’s so distant, considering the size of the Apple Family, that half the Earth ponies of Equestria could claim the same thing. Certainly nearly all of the ones around Ponyville could–it’s not that big of a town for its families not to be related somehow.
 
That said, there’s definitely some kind of a connection between Goldie Delicious and Pinkie Pie going on here.

I didn’t think it was very farfetched. Any couple of families liking in the same region for several generations are likely to be connected somewhere.

@Flammie  
 
And then Pinkie Pie found Wabbajack.

Applejack related to the Pies or Pinkie Pie related to the Apples, does that make any big difference?  
Both families are related in both cases.

@F
 
You must be the F for Fairy!
 

 
And yes Pinkie is related to everything and nothing, and something plus anything.

Maybe it’s been misread. Applejack is actually related to the Pies?

Pinkie is related to everypony.

I reckon I’m convinced.

Sure, that convinces me.
