I think this is early for Chevington. I cant find a reference this early in Earl Grey's papers at Durham University.

Slightly off topic but on the page '
Estate records of the Earls Grey and Lords Howick'
there is a reference to a Harbour for the export of Chevington Coal dated 1825;
GRE/X/P215 1825-1899
2 copy letters W. Brunton of London to Mr Taylor concerning Chevington coal and construction of a harbour for its export, 22 July 1825, with plan of the proposed harbour.
Is this reference to early (pre-Radcliffe) works on the Coquet ? .....or something else?
