30.11.1793 Johnstone at Wright's. In a row with three other performers. Hewardine and Pope were in Godwin's 1796 list for 1793 and in the 1794 version; Dignum wasn't in the list, but J H Johnstone may be the Jonstone next to Baddeley (another actor) both crossed out in the 1796 list for 1787, and also in the 1794 version.
Probably the actor and singer John Henry Johnstone DNB who died 28.12.1828
