Trefusis and his elder brother, heir to the barony of Clinton, were orphaned by the death of their father in 1797 and their mother in 1798. He was left over £10,000. The family estate was managed by trustees, among them John Inglett Fortescue and Ambrose St. John, their kinsmen, while their guardians were John Clevland and William Trefusis Reichenberg.
Trefusis had been in Italy during the session of 1817, fearing he was ‘acting very unadvisedly in absenting myself so long from Parliament’, but his mind was set at rest by his brother’s agent Francis Drake, to whom he wrote after his return home, 19 Aug.:
On my arrival I found Lord Bathurst unsolicited, had made me two proposals, one to go as consul to Tripoli with a salary of £1,000 a yr. with permission to retire after 10 years’ service with full salary, the other was a situation at Ceylon; you may suppose I did not admire the thoughts of either of these exiles.
Declining them therefore, he felt he must choose between the church and diplomacy. Princess Charlotte promised him preferment in the former, while ministers had been lobbied on his behalf in the latter case, though he himself was not very hopeful of a secretaryship of embassy.
