Over the years the spelling of Overlea has changed slightly, along with Oven Hill which is the road used to gain access to the farm. On old maps Overlea was spelt Overlee and Oven Hill road was Over Hill road.
Overlea nestles in a comfortable dip in the valley, conveniently sheltered from the wind. The original spelling of ‘Overlee’ refers to this – ‘lee’ referring to side which is sheltered from the wind.
The bridleway which runs parallel to Overlea was built to allow the coal mines to transport the coal up the valley. However, in the latter half of the 19th century, the coming of the railways largely spelt the end for local coal production. Superior quality coal was easily imported into the area from Yorkshire and Lancashire coalfields. Local mines were unable to compete and began to close. The brideleway can still be used today.
