Re Jenkins's presence in Rome at the same time as Wilson, Ashby notes:
'In 1753 we find him back in Rome: he appears in the parish registers of S. Lorenzo in Lucina as living with the landscape painter Richard Wilson in a house near the north end of the west side of the Piazza di Spagna, between the Via della Croce and the Via delle Carrozze: in 1758 he joined one John Plimer [John Plimmer, c. 1725-1761] in a house in the upper part of the Corso, on the left coming from the Piazza del Populo, a little beyond No. 18, where Goethe lived. In 1760 Plimer left him and he remained there until 1764. He was always indicated as a painter in the registers up till the year 1773; and in the session of January 11th, 1761, he was created 'accademico di merito' of the Academy of S. Luke [ ... ] His portrait indeed still hangs in their rooms.' (p. 488)
