Island of the Iroquois

Earlier today when playing as the Iroquois in Civilization III, I colonized a randomly–generated island that looks a little familiar:

Is Great Britain the island of the Iroquois?

This island looks like a somewhat angular version of Great Britain! The main continent I control is just to the west (offscreen to the left), as well as other islands farther to the north and west.
