A Vision of Britain through Time provides the following description of Burgh St. Margaret from John Marius Wilson's Imperial Gazetteer of England and Wales of 1870-72:
Burgh St. Margaret was an ancient and civil parish until 1935 when it was absorbed into a new parish named Fleggburgh which also included the parishes of Billockby and Clippesby. Fleggburgh is in the Great Yarmouth District and is located between the town of Great Yarmouth and the village of Acle.
