Protestation Return - Belchamp Walter - 1641
Having found the digital archive on the parliament website I came across the return for Belchamp Walter.
A Protestation Return was an "oath of allegiances,
the first of which was the Protestation.
It began in May 1641 with the intention of getting all Englishmen above the age of 18 to swear a vow to
defend King Charles I and the Church of England.
Ultimately it failed and tensions continued to escalate between Parliament and King Charles I,
eventually leading to the start of the English Civil Wars in August 1642".
It is interesting that the return seems to have been completed in the same hand-writing.

Who signed (see here) the Protestation in Belchamp Walter
John Raymond (1st of Belchamp Walter) and his son Oliver (member of Oliver Cromwell's Parilament) both signed. Other names are discernible including William Smythies, Swift, Clark, Firmin, Sparrow, Newman and possibly Rippinggale plus many others.
Note that Oliver Raymonds name is at the top and the return is completed in the same hand.

According to parliament.uk:

Signing
The parliament website goes on to say about who signed the return:
But usually a local official wrote out all the names.
