[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.

George's brother Robert built a home at Castleton, Rockcliffe CA6 4BN in Cumbria (still owned by descendants and sadly not open to the public) - there is an article with further family information here:
The Clergy Database says that Dorothea's grandfather, the Rev. Robert MOUNSEY. was initially a schoolmaster in Orton, Westmorland, and then perpetual curate of St.Oswald's, Ravenstonedale, Westmorland from 1735 until his death in 1780. There is a plaque comemorating him inside the church, which suggests he was actually the minister at St.Oswald's from 1729. The plaque reads:
Near this place are deposited the mortal remains of the Revd Robert MOUNSEY, CI. (51.years Minister of this Parish) who departed this life 29th March 1780, in the 84th Year of his Age; and of Mary his Widow who died 23rd March 1786, in the 85th Year of her Age; Also of Mary their Daughter, who died in the Year 1755 Æt. 32.
