The younger William is at home with Father Richard on a property called Six Acres .. in 1851
Here's the older William in 1851 - the Farm is 160 acres, called 'Coffins' - the 20th dwelling on the Enumerators 'walk' - and close by 'Six Acre' ... the District description doesnt help locate it, but does name a mixture of hamlets and farms that a local might piece together.
Later census may be more specific ...
