On this site, which was short-listed for the SAHGB Colvin Prize in 2019, I present the results of my research into the landowning families of the British Isles and the country houses which they owned. Comments, especially in the form of corrections, additional information or new illustrations, are very welcome. Please use the Contact Form in the right hand side bar to contact me privately or the comments facility at the bottom of the page to make a public comment.
