 There are few historical references to Govan in the interim, though there appears to be one reference included in Simeon of Durham's ‘Historia Regum Anglorum’, compiled sometime in the 12th century AD.In it, Simeon records the return of the Northumbrian army from Ovania after attacking Dumbarton in 756 AD.Originally, the Annals of Ulster recorded Dumbarton Rock as the centre of the British Kingdom of Al Clud (usually pre-emptively referred to as the Kingdom of Strathclyde, but which is more accurately described as ‘the kingdom on the Clyde’) from the 6th century AD until the later 9th century AD.
