Mason was a medieval settlement located in what is now the north-eastern side of Dinnington (presumably from which the Mason's Arms public house in Dinnington takes it's name). Mason was first documented as "Merdesfen" in 1190AD, and 8 taxpayers were recorded here in 1296. Much of the settlement was lost in the Middle Ages, probably abandoned. In the 19th century Mason was a township. It included North Farm (still surviving) and South Farm (no longer exists).
