of Charlecote, Warwickshire. Alice Grey, married Sir John Knivett, a descendant of Sir John Knyvett Rebellion of Owain Glyndŵr In 1410, after a long legal dispute, the younger Reginald won the right to bear the arms of the Hastings family, but rather than the undifferenced arms which were born by the Hastings of Sutton he won the right to the higher status quartered arms born by his deceased cousin the Earl of Pembroke: Hastings quartering Valence. Since he had gained the right to bear these arms from his claim through his paternal grandmother, he displayed Quarterly 1 & 4: Grey de Ruthyn; 2 & 3: Hastings quartering Valence. (Sir John de Grey displayed the new family arms with a label argent for difference from his father's arms). More important from a financial perspective, he gained title to certain properties of the estate. De Grey enjoyed the favour both of Richard II and Henry IV, and his chief military exploits were against the Welsh, during the rebellion of Owain Glyndŵr.

Under King Richard II the case had been found in favour of Glyndŵr, but on the usurpation of King Henry IV of England, Lord Grey seized the land. Early in September 1400, Henry IV left Newcastle and travelled south to Northampton, which he reached by the 19th. There news reached the King of the quarrel that had broken out between Grey and Glyndŵr. Grey was a member of the King's Council.

Such an act as refusal or failure to respond to an order of the King was deemed a treasonous act. Glyndŵr's estates were deemed forfeit until he could prove his loyalty or receive due punishment.
