Mountstuart Elphinstone Grant Duff, Dictionary of National Biography (1901)
“ The Bruce family was Scottish, but an ancestor had come south and bought, in 1747, the Duffryn estate in Glamorganshire, where John Bruce long lived, and which ultimately became his property and descended to his son. The old house, which Lord Aberdare rebuilt in 1870-1871, dated from Edward II. Bishop Copleston, writing of a three days' visit to the father, John Bruce, at Duffryn in 1834, says that the 'domestic scene realised his ideal picture of a highland chief among his vassals, all looking up to him with affection and veneration. ”
