Francis Cecil Legge, Dictionary of National Biography… (1900)
“ Robert Wilberforce's sudden death deprived the Roman church of a valuable recruit. He was utterly without personal ambition, but with a great power of identifying himself with any cause he took in hand, and his earnestness seems to have made a profound impression on all with whom he came in contact. At the same time, he was better trained in theological and other academic learning than either Newman or Manning; and there is little doubt that had he lived he would have become as prominent a figure in controversy as any of his fellow-seceders. ”
