Hurle is an uncommon surname and (internet sources suggest) that he may have been Henry Hurle (1739-95) of Garlick Hill, London who was a carpenter, surveyor and builder. He was a Member of the Court of Common Council and also a founding member of the Ancient Order of Druids, a fraternal organisation established in 1781.
