mains

Davidson's Mains is a former village and now a district in the north-west of Edinburgh, Scotland. It is adjacent to the districts of Barnton, Cramond, Silverknowes, Blackhall and Corbiehill/House O'Hill. It was absorbed into Edinburgh as part of the boundary changes in 1920 and is part of the EH4 postcode area.
Locals sometimes abbreviate the name to D'Mains.
