History of Buckinghamshire
The name Buckinghamshire is Anglo-Saxon in origin and means The district (scire) of Bucca's home. Bucca's home refers to Buckingham in the north of the county, and is named after the Anglo-Saxon landowner, Bucca. The county has been so named since about the 12th century; however, the county has existed since it was a subdivision of the kingdom of Mercia (585–919).
