Never heard of them, but Oregon is a huge potato growing state - so maybe it was a description of where the potatoes were from??? No idea otherwise.
For those here in the States . . . . did we all know the brand Ore-ida (lots of frozen potato products, fries, tater tots, etc) is for Oregon - Idaho . . . Ore-Ida . . . . . (both big potato growing states) I can’t tell you how old I was when I first learned that (put it all together) but it wasn’t long ago enough . . .
