W. F. Spear, Dictionary of National Biography… (1912)
“ STEPHENSON, GEORGE ROBERT (1819–1905) , civil engineer, born at Newcastle-on-Tyne on 20 Oct. 1819, was only son of Robert Stephenson, brother of George Stephenson of railway fame [q. v.] . He was thus a first cousin of Robert Stephenson [q. V.] . At the age of twelve he was sent to work with underground viewers and surveyors at the Pendleton collieries, near Manchester, where his father was chief engineer. He was then trained for two years in the colliery workshops and was given charge of one of the engines used for drawing wagons up an incline. ”
