In his book " Goodwife Hot, and others: Northumberland's Past in it's Place Names" Godfrey Watson writes.....
"Plessey Checks denotes a place where coal, coming from the nearby colliery, was checked, and is called after the family of " de Plessis", who, in turn, took their name from Plaissiet. The derivation of this French word is in itself worth looking at, for it also explains PLASHETTS, a name that appears at Bavington and again in Nooth Tynedale. It means land that has been enclosed by a Plashed or Plaited fence and therefore, probably, a Park "
*Plessey Checks and Plessey lay on the boundary of Stannington and Cramlington parishes.
* The Bavington Plassetts is the one in Kirkwhelpington parish. The North Tynedale Plassetts is the Falstone one.
