The Arms of Greystock as "Barruly argent and azure, three chaplets of roses gules" were originally those of de Grymthorp, and as such were borne by Ralph Fitzwilliam at the Siege of Caerlaverock, and serve to identify his tomb effigy rescued from Neasham Priory, but were retained and quartered with the former Greystock arms by his successors. The Barony went into abeyance in 1569, after it had passed into the Dacre family in 1487 through the marriage of Thomas Dacre, 2nd Baron Dacre to Elizabeth de Greystoke, 6th Baroness Greystoke.
