Happy Meowloween!!

Sad not to see you'ns (you'n's?) on that map. Guess it's a fairly minor variant.

Yeah, that map isn't very detailed.  HOWEVER, if I may, let me refer you to the dialect study Bert Vaux did, which is great place to poke around for hours (if you're into that sort of thing, as I am (clearly)).  One of the questions is "what word(s) do you use to address a group of two or more people?", and the maps of the results are pretty great.  I'm guessing you'ns (or you'n's?) is buried within the "other" section.

Also, because I like regional variation SO MUCH, I spent a while poking around in Wikipedia and found a few things, including this excellent tidbit on possessives:

In rural Southern Appalachia an "n" is added to pronouns indicating "one" "his'n" "his one" "her'n" "her one" "Yor'n" "your one" i.e. "his, hers and yours". Another example is yernses. It may be substituted for the 2nd person plural possessive yours.

"That book is yernses." pronounced /ˈjɜrnzɨz/

(source, aka I am going to spend the next hour (re)reading all of this.  I might even make a post on my friends the double modals.)

Wikipedia also confirms that youns (and its variants yinz, you'uns, etc.) are part of Pittsburgh speech that are also found in Southern Appalachia.
