The Manor of Roundhay: 1603 - 26th February. The dependent manor of Seacroft was granted by James I to Charles Blount, Earl of Devon. In 1605 the Earl conveyed Seacroft to George Shillito Esq. of Houghton. For the next 200 years the legal dispute, whether the manor of Seacroft had ceased to be subject to the paramount manor of Roundhay, dragged on.
It (Beechwood) stayed in the Lupton family until the 1990s, though much of the land around it was sold off in the 1950s and became the Seacroft council estate.
