The arms are those of Cavendish impaling those of Prittie, as borne by Sir Henry Cavendish, 1st baronet, kinsman of the Dukes of Devonshire. He was born in 1707 and went to Ireland during the Vice-Royalty of the 3rd Duke of Devonshire, where he was made Teller of the Exchequer and, eventually, in 1747, Commissioner of Revenue. He married, as his first wife in 1730, Anne, daughter and heiress of John Pyne and it is interesting to note that his wife's arms appear on an escutcheon of pretence over the sinister coat on the present arms, even though this first wife had died sometime before 1748. In that year he married Catherine, widow of Sir Richard Meade, Bt., and 2nd daughter of Henry Prittie. Cavendish was created a baronet in 1755 and these dishes evidently form plate furnished at that time. He died in 1779.
