The Great Plague of London shut down the Bridges Street theatre, along with most of the city, from mid-1665 until late 1666. Gwyn and her mother spent some of this time in Oxford, following the King and his court. The King's Company is presumed to have mounted some private theatrical entertainments for the court during this time away from the virulent capital. Gwyn and the other ten "women comedians in His Majesty's Theatre" were issued the right (and the cloth) to wear the King's livery at the start of this exile, proclaiming them official servants of the King.
