I have a number of Barleys who were living in and around Upwell area of Norfolk (about 20 miles from Hockham I think), but have also hit a wall!
My tree stops at around 1798 with the marriage of Edward Barley to Mary ??? in Upwell. A branch of the Barleys then moved to Wisbeach in around 1830 to work on the docks and then onto Stavely in Derbyshire around 1850 to work in the mines.
