George was the son of Colonel Herbert Frederick Campbell of Evenley Hall and his wife, Louisa Cox.
[1] Campbell made a single first-class appearance for Lancashire against Surrey in 1866 at Wavertree Road Ground, Liverpool.
In their first inning, Lancashire made 125 all out, with Campbell being dismissed for 10 runs by Frederick Miller.
[4] In business, he was a partner in a firm of bankers and army agents, Cox and Company, which was formed through connections in his mother's family.
His funeral was well attended, with distinguished mourners such as Archibald Campbell, the then Chairman of the London Stock Exchange, and Oliver Fitzroy, who attended as a representative of the Speaker of the House of Commons, Edward FitzRoy.
