What tower house did David Gregory inherit in 1664?
David Gregory (physician) David Gregory (20 December 1625 – 1720) was a Scottish physician and inventor. His surname is sometimes spelt as Gregorie, the original Scottish spelling. He inherited Kinnairdy Castle in 1664. Three of his twenty-nine children became mathematics professors. He is credited with inventing a military cannon that Isaac Newton described as "being destructive to the human species". Copies and details of the model no longer exist. Gregory's use of a barometer to predict farming-related weather conditions led him to be accused of witchcraft by Presbyterian ministers from Aberdeen, although he was never convicted.
Godric of Mappestone Godric of Mappestone was an Anglo-Saxon "thane" and landowner mentioned in the Domesday Book of 1086 as a tenant of Howel in modern Herefordshire. Godric is best known for the construction of the first timber version of Goodrich Castle, probably during the late 1080s, when it was originally known as "Castellum Godrici", or "the castle of Godric". Victorian historians, however, believed the castle to date back further to the pre-Norman conquest days of King Canute, and the site may have been among a small number of Saxon fortifications along the Welsh border.
