`William took his surname from the village of Burgh Castle, Norfolk, England.'
It is highly likely that the family took its name from Burgh-next-Aylsham in Norfolk and not Burgh castle. Burgh-next-Aylsham was put forward as the most likely candidate by F.M. Powicke in ’The Oath of Bromholm’, 1941, The English Historical Review, pp. 529-48, and further information is given by Clarence Ellis in `Hubert de Burgh A Study in Constancy' pp 188-191. To summarise an itinerary survives for a visit to Norfolk by Henry III and Hubert de Burgh during which they stayed at Hubert's manor at Burgh, the itinerary only works if the Burgh in question is Burgh-next-Aylsham. Further to this Hubert built up landholdings in the Aylsham/Burgh area presumably to consolidate the fmaily estate.
