Black Velvet Band

Newry Town (I took their jewels home)

Sovay (she steals all his money, but he refuses to give up his diamond ring)

I'll tell me ma (he stole my comb)

Whiskey in the jar (he counted out his money) (also, Jenny steals the protagonist's rapier)

There's a whole family of broadside ballads in which the intended victim steals the robber's horse and finds the saddlebags stuffed with swag.

In Lovely Joan, she steals his horse and ring.

In Patrick Street/Barrack Street/New York Girls, she steals his watch, money and all his clothes.

Are you really doing a PHD on this? It seems a rather random way to do doctoral research!
