I have been looking into the Arms of Sir Thomas Masterman HARDY (of HMS Victory fame) and have found a variety of blazons;
1815 – Debrett’s Baronetage “Pheon [sic] on a chevron between three escallops Argent as many griffins’ heads erased of the field langued Gules.”
1838 – Debrett’s Baronetage “Peaon on a chevron Or between three escallops Argent as many griffins’ heads erased of the field.”
1841 – Burke’s Extinct Baronetcies “Pean on a chevron between three escallops Argent as many griffins’ heads erased of the field.”
1884 – Burke’s General Armory “Pean on a chevron between three escallops Argent as many dragons’ heads proper.”
Who to believe?
Update;
My thanks to Robert Noel, Lancaster Herald, who advised that the
details were;
Arms: Pean on a chevron Or between three escallops Argent three
dragons’ heads erased of the field.
Crest: Out of a naval crown Or a dragon’s head pean.
