[Philip's son John Philip CAMM, born ca 1800, was also a member of THORNHILL's Party to the Cape].
Adam GILFILLAN has also been frequently named as a nephew of Christopher THORNHILL but this is incorrect and probably arose from a misconception by Jeremiah GOLDSWAIN of WAIT's Party, who wrote in his diary "I was informed that the pirson had come down from London: this was Mr. Adam GILFILLAN Nesuw to Mr. THORNHILL Mr. Wm WAITs partner." GOLDSWAIN probably confused Adam GILFILLAN with John Philip CAMM, who was THORNHILL's nephew.
