I am connected to JKH indirectly. His close friend Harry Johnson (after whom JKH named his youngest son) was a cousin of my GGGrandfather John Johnson, and in his memoirs JKH recalls their uncle Robert Johnson whom he visited when he went to London in the 1840s. I can provide full info on the Johnson family to anyone interested.
JKH stated that he painted at least 2 portraits of Harry Johnson. Does anyone have any idea where these might be? I could not find the Ayrshire Museum portraits online; could you possibly post the link, please?
