How many storeys does this tower house have which David Gregory inherited 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.
Swakeleys House Swakeleys House is a Grade I-listed 17th-century mansion in Ickenham, London Borough of Hillingdon, built in 1638 for the future Lord Mayor of London, Sir Edmund Wright. Originally the home of the lords of the manor of Swakeleys, writer Samuel Pepys visited the house twice. The property changed hands many times over the years and at one time was home to the Foreign & Commonwealth Office Sports Association. Large sections of the grounds were sold off in 1922 and developed as suburban housing.
