What names did the British sailors
aboard the HMS Beagle give to the
three natives of Tierra del Fuego
they took to England as part of
an "evangelical experiment" ?

York Minster (named after the Cathedral),Jemmy Button and Fuegia Basket.There was fourth man named Boat Memory,but he died shortly after reaching England.

Those are the three I was
looking for.

Thanks for the answer Princess V~Ha !
