Thanks for the info Slowhands

Family history says that Maynard Porter walked 4 miles to the pit and earned 17 shillings per week. In the winter he would drink a pennysworth of rum to give him strength for the walk.

I'll get the map out and see what is in a four mile radius of Plump Hill. It might give me a hint as to where he worked. Not taking the family lore as gosple!
