House Cargyll was a noble house from the Crownlands. According to semi-canon sources, the house blazoned its arms with a golden goose on bendy sinister black and red. The house is currently extinct, but was still in existence at the time of the Ashford Tourney.
Ser Arryk and his twin brother Ser Erryk Cargyll were famous members of the Kingsguard. They chose opposite sides during the Dance of the Dragons, with Arryk supporting Aegon II Targaryen and Erryk siding with Rhaenyra Targaryen. The twins slew one another during the civil war.
Ser Clarence Cargyll participated in the tourney at Ashford Meadow in 209 AC, his arms spotted by Duncan the Tall among the gathered heraldry.
