And see p 185 in Sigler, JL, "GENERAL PAUL THIÉBAULT: HIS LIFE AND HIS LEGACY", unpublished PhD thesis submitted to Forida State University, 2006. Although I think Sigler is slightly erroneous in suggesting Aruago (sic) was then a, let alone a principle, member of the regency council in November 1807. The person to whom he refers is, I think, João António Salter de Mendonça (ARAÚJO) - one of the two secretaries appointed to assist the council members. Obviously, I stand ready to be corrected by someone better informed on this than I.
Best wishes
