Barbara Stevenson:
Agnes de Percy, sister and co-heir, became sole inheritor of the line which for five generations had lorded it over the North Riding of Yorkshire. Last of the original family planted in Yorkshire by William, called Algernons, she passed on the great name and heritange to the sons whom she had borne to husband Josceline de Louvain. With her burial at Whitby Abbey began the story of the second and more splendid dynasty of Percy. While the Lady Agnes de Percy, eventual heiress of her race, was in her 16th year and as yet unwedded it occurred to the shrewd Queen Adeliza, 2nd wife of King Henry I, that no fitter match than this could be found for her own half-brother Josceline de Louvain. Accordingly she hastily summoned young Josceline from Brabant, and established him at court, where Agnes de Percy was a maid of honour.
