[4][5] Edmond William Costello (1873–1949), holder of the Victoria Cross, is buried in the churchyard, and Diana Rowden (1915–44), SOE agent, lived at Hadlow Down before World War II.

century Hadlow Down was a rural farming community with the small population living either side of the main road that runs through it, it was relatively quiet and secluded.

The Wealden cannon making industry started at a furnace on the stream at Hoggets Farm situated to the north of the centre of the village.

The 'John' referred to is believed to be a French cannon maker by the name of Baude whose family is buried at Wartling on the Pevensey Marshes.

[9] Tinkers Park[10] is the home of the Claude Jessett collection of traction engines, steam rollers & fair organs is situated at the eastern end of the village.

Hadlow Down is well known for its association with steam engines similar to those being used in the local rural farming industries many years ago.

By the 1950s Claude and his wife Joyce had become interested in the embryonic steam rally scene and, by the early 60's, their collection of steam engines had grown and they were branching out into collecting fairground organs, farming equipment and narrow gauge railways.

The first annual Tinkers Park steam engine rallies was held in 1966 in aid of Cancer Research.
