John Horace Round, 1911 Encyclopedia Britannica (1911)
“ His male line of heirs became extinct on the death of Hugh “de Albini,” earl of Arundel, in 1243, who had four sisters and co-heirs. In the partition of his estates, the castle and honour of Arundel were assigned to his second sister’s son, John Fitzalan of a Breton house, from which sprang also the royal house of Stuart. It is proved, however, by record evidence, that neither John nor his son and successor were ever earls; but from about the end of 1289, when his grandson Richard came of age, he is styled earl of Arundel. ”
