You betcha. I forget just what part of Great Britain Hernan Cortez and Francisco Pizarro were from. I'm sure Huey would be glad to tell us.
I think the farthest south the British got was Belize back in their Colonial days.
Not sure of the Islas Malvinas/Falklands history. I think, though, it was to encourage settlement. There might be a few sheep ranches there...
