The eighth Earl of Darnley (the only Earl of Darnley to captain England), Ivo Bligh, truly loved Australians.
After winning the Ashes in 1882/83, he took 6 Australians back home with him.
He kept them in his garden, often playing fetch with them, wresting with them, and occasionally slipping some gin into their water bowls.
To stop them mating he had the males castrated.
Eventually he grew tired of them and since no one else wanted to own Australians at that time, he had them all put down.
