Before the Norman Conquest a Saxon named Blunda settled here and  eventually the name became Blunham. It included the present  parish of Mogerhanger, which may account for the large Church, with a Norman  arch and west door, part of which dates back to the 12th century. Until 1799 the  village was part of the estate of the de Greys of Wrest Park,  Silsoe.

Mainly an agricultural village of just over 1,200 acres, Blunham  has some 860 residents, many of whom are commuters. Old and new buildings,  however, present a good degree of compromise; such as Manor House and the new  Manor Court. The centre is compact and in part subject to a Conservation Order.  The parish contains one of the few remaining pounds in the county.

Local  facilities include a butchers, fish and chip shop, Post Office/General store and  Lower School. There is a recreation ground in the village and a mobile library  visits weekly. Bedford, Biggleswade and St Neots are each about 7 miles away.
