1747 Flora MacDonald by Richard Wilson (National Portrait Gallery - London UK)
Charles Edward Stuart tried to overthrow the UK government, that had turned to the Hanover family, in 1745. He marched into England and his army was chased back into Scotland and wiped out at Culloden Moor. Bonnie Prince Charlie had to escape and Flora MacDonald helped him to get out of the country, alluded to by the boat to left. She married Allan MacDonald in 1750. Ironically, she emigrated to the colony of North Carolina in 1774 and supported the Crown when the colonies rebelled. She returned to Scotland in 1779, when she was wounded when her ship was attacked by a privateer en route. She died on the Isle of Skye in 1790. Her Wikipedia article is here.
