[2] Perrone's residency in London was associated with a strong emphasis on Sardinia's commercial interests in Britain.
[3] In late 1752 and early 1753, he was involved with the negotiations between Charles Emmanuel and Archbishop Herring regarding the possible translation of the relics of St Anselm from Canterbury Cathedral to Aosta in Sardinia (now Italy).
[4] The archbishop was not averse to the idea[6] and Perron's investigation was of the opinion that Anselm's remains were probably intact and misidentified as Theobald's,[8] but the matter was uncertain[11] and seems to have been dropped.
[9] The archbishop's original plan to foist "any other old Bishop with the Name of Anselm" "on the Simpletons"[6] was foiled by the ambassador's insistence that he personally witness any excavation to procure the remains.
[3] In 1784, he used his connexions to secure the appointment of his son-in-law's brother, the Cavaliere Nomis di Pollone, as resident minister in London (until 1787).
