Under the heading "Sporting Intelligence" The Newcastle Journal of 9 September 1837 reports that "William Watson, Esq. of North Seaton, and Edward Riddell, Esq. Cheeseburn Grange, are appointed Stewards for Morpeth Races next year". This text matches the newspaper clipping attcehd to the broadside in the Bodleian Library. the Census of 1851 records a J.C. Watson living at North Seaton Hall. He would have been aged 22 when the broadside was printed, so he is probably the eponymous coachman
