In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Barnham like this:
BARNHAM, a parish in the district of Thetford and county of Suffolk; on the Little Ouse river, 3 miles S of Thetford r. station. Post Town, Thetford. Acres, 5,184. Real property, £2,455. Pop., 475. Houses, 87. Some tumuli in the N are supposed to mark the scene of a conflict, in 870, between King Edward the Elder and the Danes. An ivy-clad square tower belonged to the church of the extinct or incorporated parish of Barnham-St.-Martin. The living is a rectory, annexed to the rectory of Euston, in the diocese of Ely. The church was restored and enlarged in 1864. There is a free school.
