House & Family History: Lord Byron spent his infamous 1815 honeymoon (he referred to it as their "treaclemoon") with his wife, Anne Isabella Noel Milbanke, at Halnaby Hall. The couple separated in 1816 and the physical remnants of their marriage have been collected ever since. The Keats-Shelley House in Rome has on display a piece of red damask from the Byrons' honeymoon bed at Halnaby; on December 13, 2018 another piece of fabric from the bed was sold at auction by Dominic Winter Auctions for £1,600, against an estimate of £2,000–£3,000. Halnaby was noted for its Rococo plasterwork.

Collections: A carved and gilded wood Rococo mirror from Halnaby, made in London, 1758-60, probably to the designs of Thomas Johnson, is today in the collection of the Victoria & Albert Museum, London.
