Burnham lay in the Hundred of Brothercross, in territory held after the Norman Conquest by Roger Bigod, Hugh of Montfort and the abbot of Ramsey, who from 1087-1091 was Herbert de Losinga, subsequently Bishop of Norwich. The Burnham parishes, originally nine, all lie within a mile of Burnham Market, the largest of them. Collectively the Burnhams constituted an ancient estate which evolved into a flourishing mercantile centre, probably with the establishment of a market in the 13thc, when, in addition, the river Burn near which they lay, was still navigable. Burnham Ulph was amalgamated in 1422 with Burnham Sutton, whose parish church was demolished in 1771.
