In the A Song of Ice and Fire novels, Claw Isle is the seat of House Celtigar. It lies a few hours sail from Dragonstone. Similar to House Velaryon of Driftmark, the Celtigars were followers of House Targaryen when it originally fled from Essos to avoid the coming Doom of Valyria. They are therefore of Valyrian descent. These refugee Valyrian families survived on islands in Blackwater Bay for another century: the Targaryens on Dragonstone, the Velaryons on Driftmark, the Celtigars on Claw Isle, and possibly others. During the War of Conquest they provided troops to their Targaryen liege-lords, which made up the small original core of Aegon the Conqueror's army.
