Coat of arms of Pembroke

The blazon

ar. a wolf, statant, gu. on a chief, indented, of the last, three fleurs-de-lis of the first, and the same crest. [ Certified at the College of Arms, London, June 1772, to William Pembroke, Lisgr.]

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.
