As banshee is a "wailing woman" I doubt her father is one :) if you dont trust me, check wikipedia for banshes, they are all women :)

As for Perish, I think he is a hellhound.

You know what else Wikipedia has? A page for Banshee (Comics) that holds information about the Marvel comic book character named Banshee and has "wailing" powers related to the myth. He is a male.

The point is that any show can take the concept of real world mythologies and change any part of that myth for their own ends, thus establishing a new mythological creature with a shared name. You cannot apply real world myth facts to other mediums since those mediums can and often do deviate from the real world. To do so is false and will confuse those learning about the Banshee legend on Teen Wolf.
