A question has been posed about the surname of Daniel Chatto, the husband of Lady Sarah Armstrong-Jones. Daniel was born Daniel Chatto St. George Sproule on April 22, 1957 at the Princess Beatrice Hospital, Kensington. He was the son of Tom Chatto St. George Spraule and his wife, the former Rosalind Thompson. The birth was announced in the Times several days later .. in the births column, under Sproule. Tom Chatto St. George Sproule (pronounced Sprawl) was an actor, who used the name Chatto as his stage name. His father, James, who was born in Melbourne, Australia, came to London after the first World War, to marry his second cousin, Gladys Chatto, whose family founded the publishing house Chatto & Windus.
When Tom became an actor, he adopted the use of his mother's surname as a stage name. On September 28, 1987, the London Gazette published a notice that "by Deed Poll dated 26th June 1987 and enrolled in the Supreme Court of Judicature on 18th September 1987, DANIEL ST. GEORGE CHATTO ...a Commonwealth citizen, abandoned the name DANIEL CHATTO ST. GEORGE SPROULE and assumed the name DANIEL ST. GEORGE CHATTO."
Tom Chatto died in 1982. His widow, Rosalind, a literary agent, also uses Chatto as a surname.
Contrary to some rumors at the time of Daniel's engagement, Daniel is not the son of Robin Fox, nor is he the half-brother of Edward Fox. He is the son of Tom Sproule and Rosalind Thompson.
