There's a Hunting Sporran being sold on Ebay

https://www.ebay.com/itm/sporran-rea...p2056016.l4276

and in the listing the seller states

"The five stripes at the bottom represent the five dominant families in Scotland."

First off, my tendency is to dismiss out of hand all such claims about features of clothing being put there to represent something. The features usually predate the event that they're supposed to represent and/or can be shown to be bogus through other means.

The "five stripes" the seller mentions are the fish-shaped tabs usually seen on Hunting Sporrans in place of tassels.

But is there such a thing as "the five dominant families of Scotland"?

Which families would those be?
