Dr William T. Angove registered a trademark for his wine business in 1908. It comprised a double-headed eagle with wings and legs outspread. Its origin is not known with certainty, but prior to this, in January 1883, in a letter to his brother Edward, he wrote, ‘Will you send me one of the crests you had done: say how you found out all about it.’  Edward Angove’s reply to this question has not survived but Dr Angove’s grandson, Tom Angove, possessed a gold cygnet ring that belonged to Edward Angove bearing the eagle crest. Tom inherited it from Edward’s granddaughter by marriage, Mrs Kate Garbett, in 1961.

Prior to this, in 1948, T.C. Angove approached the College of Arms, London with regard to registering the Armorial Seal – a spread double-headed eagle – from the Angove Coat-of-Arms as a trademark. Investigations by the College of Arms found that the arms were those of Abell/Abel Angove (1673-1741), of the Parish of Illogan. However, the College of Arms had no Arms for the name of Angove and suspect that the Arms being investigated may never have been officially recorded.

The outcome of the searches was that the College of Arms was unwilling to confirm the supposed Angove Arms, but were prepared to incorporate the principal feature, the double-headed eagle, slightly modified, in a new granting of Arms. The new shield depicts the family interests of mining and winemaking, with a motto of Deo Volente Vincam, God willing, I shall conquer.

T.C. Angove died before the Coat of Arms was granted, so when the grant was made on 20th May 1953 by Queen Elizabeth it was to his son, T.W.C. Angove. Soon after this, the Armorial Seal was incorporated into the design of Angove wine labels and has been used ever since in this manner.
