The parish touches Fledborough, Normanton on Trent, South Clifton, Tuxford and Weston.

Low Marnham traditionally had the higher profile in the past because of its now dormant parish church and school/village hall.

The lane runs nearby the River Trent before looping back to the Sutton-Rampton road.

High Marnham presently maintains more amenities such as a public house, caravan site and park homes, but became prominent with the presence of the former ferry to South Clifton across the River Trent, and particularly with High Marnham power station being sited close to the village.

Outside of this is a light scattering of farms, farmhouses, auxiliary buildings and cottages amongst a wider mainly farmland setting.

The name "Marnham" means 'Mearna's homestead/village' who was an Anglo Saxon local, although little knowledge on this owner exists.

[9] Low Marnham has a notable connection to the early 17th century Protestant movement and the ‘Mayflower Trail’ which usually tracks the development of Puritanism from Babworth to Scrooby and Austerfield.

The ‘Mayflower’ route particularly begins here, because it is where the spiritual leader of the Scrooby separatists, Richard Clyfton started in his first capacity as vicar briefly in 1586, before taking up the post at Babworth only a few months after.

[10][11] It is also where John Smyth, the first Baptist, was involved in a riot, possibly to help gain control of the chapel from Puritans, and taken to court in 1604.

For 250 years they were the dominant family here and their memorials carpet the sanctuary floor in the Low Marnham church.

There was the explorer 'Labrador' George Cartwright who brought a small group of Inuit to stay at Marnham although most died of smallpox soon after.

George ran out of money and the Hall had to be bought back from the mortgage by the younger brother John.

He further tried to help out his brother Edmund, a clergyman who invented the power loom in 1784 but who then got into difficulties trying to run a textiles business.

Jack sold Marnham to the Brownlows and moved to Lincolnshire, after which there was refurbishment involving part of the hall being demolished and rebuilt around 1789–1793.

JG Pears is an animal feed and fertiliser manufacturing facility, located to the south of Low Marnham.

[29][30] The line continued to be used for through traffic until 1980, when the route over the River Trent/Fledborough viaduct was permanently closed off after a derailment.

The trackbed east of the railway station location, which runs over the Fledborough viaduct as National Cycle route 647,[31] is joined within Marnham parish.

St Wilfrid's Church at Low Marnham dates from the 13th century, and was closed as a site of worship in 1986.
