The naming of Belchamp Walter
The "Walter" Part
It is often asked how Belchamp Walter got its name. The most common explanation is that it is due to a connection in its history to Walter de Tey.
I previously discussed this on my page "The derivation of the name Belchamp Walter", this page is an expansion on the possibility of the connection with Walter de Tey.
Isabel de Steyngreve
Isabel de Steyngreve was the daugter of John de Steyngreve, who died in 1295 (according to Thomas Wright).
If I assume that Isabel didn't pre-decease her father and the Walter de Tey I have featured was born in 1260 they must have married around the 1280's. This was Isabel's second marriage (according to ????), her first was to Simon de Pattishall, (who died in 1296).
Philip Morant and the alternative names for the village
The spelling on Beuchamp above is either a spelling mistake on my part or was in the original text taken from the VH website. In any case the spelling does not appear in Morant's text and Domesday is, as usual, subject to a lot of interpretation. Also the spelling of Domesday as Doomsday is a clue.
