Stansted Montfitchet
There is definitely a connection to Stansted Montfitchet to Belchamp Walter but there is no entry in Thomas Wright. However, there are multiple references to the Gernons of Stansted Montfitchet.
The Wikipedia page says:
The church of St. Mary the Virgin is situated between the village and the M11. Stansted airport is on the other side of the motorway.
