House Farman of Faircastle

Before the Westerlands answered to a single lord, the Farmans already sailed the waters around Fair Isle. Back in the golden age of the First Men they styled themselves kings, and their ships helped turn back Ironborn raiders.

That independence ended when the King of the Rock, Tommen I Lannister, built a fleet of his own, conquered the island, and married the last Farman king's daughter — from then on the Farmans knelt to Casterly Rock.

Later, a Farman named Gylbert led the common folk in revolt against Ironborn rule and won Fair Isle back.

When Prince Aegon Targaryen fell in the battle fought beneath the Gods Eye, his wife Rhaena fled to Fair Isle with their twin daughters and found shelter under Lord Farman's roof. The refuge did not last: Tyanna of Pentos tracked them down.

Soon after, Lord Dalton Greyjoy seized the island and made Lord Farman's daughters — all five of them — into salt wives, divided between himself and his brother Veron.

Two years after the Great Spring Sickness, Lord Dagon Greyjoy struck the island again, carrying off a hundred women along with half its wealth.

Around that time, Ser Duncan the Tall weighed leaving Ser Eustace Osgrey's service to offer his sword to a Lord Farman busy shoring up the island's defences.

At another time, the Farmans rose up against Casterly Rock and against Tywin Lannister, their liege lord.

The answer was not an army: a single singer sent to the island to perform The Rains of Castamere was enough to remind the Farmans what betraying the Lannisters cost. Lord Farman took the hint and dropped the revolt.
