As long as people remember this has been the name of the unmade road to Hixham Hall. Popular speculation says that some terrible deed happened there, but Mr. Brazier reckons that it may have been originally named "Cut through" Lane, as the lane is the shortest route to the Hall and Farm.  The alternative route would be by the Heath which was considerably longer from the Pelham area, and especially in those days.

Peter Totman (NZ) offers this explanation: There are a number of fields on the farm named "Croft" such as Kilcroft, Piggotts Croft, Longcroft, Petit Croft (the latter being a corruption of Pear Tree Croft established from early title deeds). These have been anglicised in their pronunciation and are in each case called "Croat". My understanding from those I have spoken to is that Cut Throat Lane is probably a variant on Cut Croft Lane i.e. Cut "Croat" Lane.

When we go for walks around the village, did you ever wonder why people say, "I'm off round the "hat" with the dog, or "We're going to go round the bonnet"?
There are two reasons, both interdependent:

"Furneaux Pelham is one of three Pelham villages each of which was owned by the Furneaux (pronounced furnix) family in the 13thC.  It had for long, close connections with the Bishops of London and remained "extra-parochial" until 1836.  The church is rather grand - fine perp work in flint with a big tower and a two-storey embattled S porch; inside there is much to admire, particularly the stained glass by William Morris and Burne-Jones in the S chapel. The countryside around the Pelhams gives the impression of great remoteness; it combines the low hills and valleys of Hertfordshire with the large, hedgeless fields of East Anglia; the narrow lanes wander inconsequently between high banks".
