When the coastline in the area of Albany was being mapped in the late 1700's the reigning British monarch was George III and it was said that through illness he had become unstable! King George III always insisted that he was related to the Plantagenet lineage of kings even though they had ruled many hundreds of years earlier.
Human nature tells you if your boss is unstable, and related to the Plantagenet line, keep them happy. One such way is to work their name into new place names - hence King George Sound and the inland areas of the Great Southern being called Plantagenet country.
Captain George Vancouver is the only early explorer to have claimed a landmark in the name of his king. Those before him had been a lot more selfish in their approach and named land forms after their ships, themselves and their friends!
