Earlier today I found a website showing papers relating to the auction of the main Cayley estates at Brompton, Yorkshire in 1953 by the then baronet, Sir Kenelm Cayley. You can look at them at http://www.aew-fam.demon.co.uk/famtree/Letters/CayleyEstate.htm. They make some quite interesting reading! One thing that seems to emerge is that many of the lots into which the estate was parcelled did not reach their reserve price.
Sir Kenelm had sold other lands at Ebbertson and Allerston in 1920, and he sold Ebberston Hall in 1941 to my late distant cousin William Ross de Wend Fenton. In 1957 he put Brompton Hall, the seat of the Cayley baronets, up for sale.
