The 1st Baron signed and sealed the Barons' Letter of 1301 to the pope (as "Dominus de Ravensthorpe", "lord (of the manor) of Ravensthorpe") and was present at the Siege of Caerlaverock Castle in Scotland in 1300, when his armorials, a version of the arms of the senior line differenced by a fess vair (as seen on his surviving 1301 seal), were blazoned in verse in the Caerlaverock Roll.
