The Anglo Saxons - Ulwin/Unwin
This page describes the period before Conquest, what was happening in the region of Belchamp Walter.
The main thrust for my history of the area relates to the period between Domesday and the "Modern" era - pre 1611, i.e. the period before the Raymond's were owners of the Manor of Belchamp Walter.
The date on the Belchamp Walter Village sign - What the 904 date on the Belchamp Walter village sign means
The quest to confirm the 904 date (possibly 940AD or even 94AD) - There are multiple references to Ulwin/Unwin also known as Wulfwine as being the ruler of the region pre-Conquest. (I need to add links to my references here)
Many accounts of local history make reference to Doomsday, but that in itself is not really helpful. I think that a quote from F.W.Maitland is to the point: The "Domesday Book appears to me, not indeed as the known, but as the knowable.", the language used and the interpretations are key.
Using Domesday as a basis for a historical account is fraught with problems.

Earls Colne
The Manor of Earls Colne. It is interesting that the history of the Belchamp Walter region is tied to Earls of Oxford. - Aubrey de Vere I, II and III (Aubrey de Vere III was the 1st Earl of Oxford, appointed by the Empress Matilda (Henry II)
A quote from the Wikip page:
Castle Camps - another reference to Aubrey de Vere (Earl of Oxford)
The de Vere family name seems to be synonymous with the Earls of Oxford. It spans 20 Earls over 600 years. The gene.com page for the Unknown father of Aubrey de Vere has an interesting quote:
This seems to stem from the fact that the father of Aubrey de Vere is not known and the de Vere name lasted for a long time.
Colne Priory
From Wikipedia on Colne Priory:
Clergy for Belchamp Walter were sent from the priory Jon. Clark, and Richard de Oakham 1370.
Ulwin - Wulfwine
There are many references to Ulwin/Wulfwine in many accounts of pre-conquest times.
The Prosopography of Anglo-Saxon England (PASE) mentions Belchamp Walter in the account of land "transferred" from Anglo-Saxon to Norman ownership.
