Disclaimer: This page is in progress. I am just trying to make sense of what I see and interpret from what I can find. Some of what you may find here is my opinion and I may have got a few dates wrong. I am not a historian but I am fasinated by it. My education in the matter is sorely lacking and I am trying to catch up!
In relative terms a lot has been recorded in relation to the history of the village of Belchamp Walter. In fact, since the Norman Conquest the history of the village has formed a key reflection of what was going on in the country in general. In a similar manner to other villages in the UK there really wasn't a lot going on before the Conquest. True the Romans included Great Britain in their Empire but the Anglo Saxons and Celts left little in comparison to be talked about. The adoption of Christianity and series of monarchs is recorded and some structures such as St. Peters on-the-wall at Bradwell and burial mounds at Sutton Hoo are known. Many communities have places of worship that originally date from pre-Conquest times, as does Belchamp Walter.
I do not wish to dismiss early British History but the period post Conquest, with the Doomsday Survey, started the major documentation of historical events. The recorded history of Belchamp Walter pretty much starts with Conquest as the inhabitants played significant roles in the countries history. De Vere was installed by William in Essex and the Botetourts came over with the Norman invasion. The lands and Manor were under the control of De Vere and Botetourt lived in the region and probably in Belchamp Manor house. The current Raymond family has both ties to Conquest and to other significant events in British history.
The Raymond family married into Conqueror lineage in 1653 after purchasing the manor in 1611 returning to the region from Kent. Phillip Raymond, in the 16th century married a country heiress from Hunsdon (Essendon), Hertfordshire. It was thier great-grandson John purchased Belchamp Walter from the Wentworths in 1611.
I would say that the most significant event relating to English history is the Raymond's involvement with the Cromwell Parliament. The evidence of which can clearly be seem in the church. Oliver Raymond served as knight of the shire in Cromwells parliaments in 1653 and 1656. The removal of most of the memorials to earlier "monarchists" (Botetourts) was probably due to this. Thomas Wentworth, 1st Earl of Stratford was beheaded by Cromwell in 1641. This is in stark contrast to the involvement of Sir William Harris in the Spanish Amarda (1588) and knighted by James 1 in 1603. This seems pretty "royalist" to me! Defending Elizabeth 1 from the Spanish, only to have a son-in-law "go over to the dark-side" and be complict in beheading those that followed the King.
Again, this is documented in the church, the Reverend John Wright 1650. Charles 1 was executed 1649. Then William Raymond in 1679 was the patron (and appointee) of the Reverend John Bate, presumably a puritan. Turbulent times indeed! and we think Brexit is bad.
The Village Name
I have also seem Parish registers with the name Walter Belchamp, changed by hand to Belchamp Walter.
I have doubts on the association with Walter de Tey - I have seen court records from the 1700's with the manor names of Water Belchamp alias Belchamp William
After the Civil War
Starting my research from what I see in the church.
