Coat of arms of Cory

The blazon

or, three mullets, and a chief gu. charged with as many griffins heads erased of the field. [ Granted to Thomas Cory, of the Inner Temple, London, Chief Prothonotary of the Court of Common Pleas, and one of the Benchers of the said Temple, 18//t March, 1639.]

A blazon is the description of a coat of arms in the technical language of heraldry. The drawing comes from that text, and from nothing else.
