Unmentioned in the "Domesday Book" of 1086, Royton does not appear in records until 1212, when it was documented to have been a thegnage estate, or manor, comprising twelve oxgangs of land, with an annual rate of 24 shillings payable by the tenant, William Fitz William, to King John. From William, who died in 1223, Royton passed to his son Thomas, who was still alive in 1254. Thomas's daughter Margery, who married Alexander Luttrell of Somerset, sold the majority of Royton and its outlying land to John de Byron in around 1260. It is from this exchange that the Byron family came to use Royton as their chief place of residence until the early part of the 17th century.
