Hartley Lloyd published Solitary Hours (1834), printed by Banfield, Ilfracombe. Various attempts we're made to identify him in the Nineteenth Century but they all failed. He is not on the standard genealogical websites or British Newspaper Archive.

There was a Devon & Cornwall Notes & Queries note on him (vol. 14) 1927, p. 374 but I can't access it in Switzerland and it may not have identified him.
