Langdon Hills appears in the Domesday Book as Langeduna, being derived from the Anglo Saxon meaning 'Long Hill', 'Lang' meaning 'long' and 'Dun', as we know, meaning 'hill'.
For some reason the two parishes of Laindon and Langdon Hills over the centuries have confused the historians.
Muilman, in his 'History of Essex by a Gentleman' written in 1772, refers to both being called Langdon.
Morant wrote in 1768, in 'History of Essex', as well as Chapman and Andre's map of 1777 refers to Laindon as 'Langdon Clay'.
At some stage it would appear that the authorities tried to clearly distinguish the two by adding 'Hills' to Langdon, which technically means you are now saying 'Long Hill-Hills'.
All that has happened is a further confusion, as people started to refer to Langdon Hills as Laindon Hills, and still do to this day.
