This is the period when we first see written evidence of life in the village of Somersham. It is clear that the village was a major manor in Anglo Saxon times, though it is debatable as to whether there was a significant "Manor" house here throughout the period. The Domesday entry is helpful in that it shows a large settlement and certainly plenty of villagers and livestock.
By the end of the period the manor had changed hands from a secular lord to the church and there is some suggestion that a more substantial manor house was under construction.
Note the fishponds in the Domesday entry. The largest of these is still visible as the sunken field at the bottom of Church Street. The fishery at Somersham was one of the largest in the region and would have been used to stock eels and pike/perch
