Note 114 — Chapter V
Reading edition
"With respect to the son born of this marriage, and said to be still living at the Cape of Good Hope, I think ... there must be some mistake. I was at the Cape of Good Hope in 1830, and spent some time at Mr. George Rex's hospitable residence at the Knysna. I understood from him that he had been about thirty-four years in the colony, and I should suppose he was about sixty-eight years of age, of a strong, robust appearance, and the exact resemblance in features to George III. This would bring him to about the time, as stated in Dr. Doran's work, when George III married Hannah Lightfoot. On Mr. Rex's first arrival at the colony, he occupied a high situation in the Colonial Government, and received an extensive grant of land at the Knysna. He retired there, and made most extensive improvements. His eldest son named John—at the time I was there, lived with his father, and will now most probably be the representative of George Rex."—William Harrison: Notes and Queries, February 9, 1861.
The statement contradicted by Mr. Harrison had appeared in Notes and Queries, October 24, 1868: "When the Duke of Edinburgh went sporting in Cape Colony he was attended by George Rex and family, according to The Times account."
