16.9.1806 Curran & Hetherington call
No clear identification. The only instance of this name in Godwin's diary. The format above does not mean he called with Curran, though he may have done. Andrew Hetherington & John Mackie wholesale perfumers of 40 Drury Lane went bankrupt and dissolved their partnership in October 1806. An Andrew Hetherington was buried 2.3.1814 at St James Westminster age 35 from Cumberland St, St Pancras. A William Hetherington of 31 Skinner's St, Somers Town was one of the spectators crushed to death at the Old Bailey in the crowd witnessing a hanging on 23.2.1807. Skinner's St, though in Somers Town, was some way from the Polygon where Godwin lived, and was different from Skinner Street where Godwin lived next. These are just my favourite two possibles, see work notes for more
