Edmund Ros or Roos, 10th Baron Ros of Helmsley (c. 1455 – 23 October 1508) was a follower of the House of Lancaster during the Wars of the Roses. He regained his family title after the accession of King Henry VII of England. Family Edmund de Ros, born about 1455, was the only son of Thomas Ros, 9th Baron Ros (9 September 1427 – 17 May 1464), and Philippa Tiptoft (c. 1423 – after 30 January 1487), daughter of John Tiptoft, 1st Baron Tiptoft and Powis. He had four sisters: Eleanor Ros, who married Sir Robert Manners of Etal, Northumberland. Their son was George Manners, 11th Baron de Ros. Isabel Ros, who married firstly Sir Thomas Everingham, secondly Sir Thomas Grey, and thirdly Sir Thomas Lovell. Margaret Ros. Joan Ros. After the death of the 9th Baron, his widow, Philippa, married firstly Sir Thomas Wingfield (d. 1471), by whom she had no issue. After his death, she married Edward Grimston, esquire, (d. 23 September 1478). Career As a result of his father's attainder, he went into exile. Under Henry VII, who united the houses of York and Lancaster, the attainder was reversed; and Edmund, Lord Ros, was reinstated in his ancestral property; Belvoir had been in the possession of the Hastings family for more than twenty years. In the petition to parliament presented by Lord Ros in November 1485, his claims are stated with great moderation, and his sufferings for his loyalty to King Henry VI are not overstated. About nine years later, Sir Thomas Lovell, who had married Isabel, Edmund's sister, presented a petition to parliament, stating that Edmund was "not of sufficient discretion to guide himself and his livelihood; nor able to serve his sovereign after his duty" and asking "that he might have the guidance and governance of the said Edmund" and all his property. An Act of Parliament was passed giving full powers to Sir Thomas Lovell over the person and property of Lord Ros, and entire possession of the latter at his death upon trust for the other relatives of Lord Ros, reserving only a rent of seven hundred marks to the King, and the right, title, and interest of those who have, or ought to have, possession or occupation of certain portions of the property. Edmund, Lord Ros, lived at the manor of Elsinges, at Enfield, which he had inherited from his mother, and
