More may be added to the earlier biography.
The recent publication of a series of letters and other documents relating to the Arneburgh family has revealed something of Thornbury’s part in the tangled affairs of that family. Immediately before her death in November 1443, his kinswoman, Joan, one of the daughters and coheirs of Sir Geoffrey Brokholes by Ellen Roos, made a settlement of her estates in Hertfordshire, Essex and Warwickshire, naming him as a feoffee and remainderman. After Joan died he made life difficult for her widower and executor, Robert Arneburgh, by refusing to co-operate with him. Arneburgh claimed that she had willed the sale of all her fee simple lands while awarding him first option of purchase, and that Thornbury was thwarting the will by refusing to release his interest in them. Why Sir Philip should have done so is not clear, but if he had designs on the lands himself he was to be disappointed for, in July 1453, arbiters awarded them to Joan’s niece, Ellen, and her second husband Ralph Holt.
Just under four years later, Thornbury made a resettlement of his own estates. By means of a final concord levied on 3 Feb. 1457, he took a life interest in his manors of Bygrave and Little Munden, after which Bygrave was to pass to his son-in-law and daughter, Nicholas and Margaret Appleyard, and to Margaret’s sons, and Little Munden to the Appleyards’ daughter Elizabeth and her husband, William Bastard*, and to Elizabeth’s male issue.
Richard did not long survive his father, dying ‘ex morbo pestilenciali’ in London on 15 Dec. 1458.
