A History of the County of York North Riding: Volume 2 (p. 5) says "Jordan Foliot died in 1299. His son and heir Richard, then aged fifteen, seems to have died young, and to have been succeeded by another Richard, his son, who never attained his majority. The manor was in the hands of Sir Amphorus de Vere until Richard died in or about 1325, when his heirs were his two sisters Margery and Margaret, of twelve and eleven years of age respectively. The wardship of the co-heirs was purchased by Isabel de Hastings and Ralph de Camoys. Isabel married Margery to her son Hugh and Margaret was married to John Camoys son of Ralph. The estates of Richard Foliot were divided between them in 1330."
