sir James Pennethorne. Known as architect for the Victorian era along with John Nash. James designed the ballroom onto Buckingham palace and was knighted for the service. James had a daughter named Roddice and she is my great grandmother.  Roddice gave my gran a signate ring on her 16th birthday with the Pennethorne crest on it. It is a standing greyhound that has a crown around its neck vs a collar. My gran recently passed and we did not find her wax for the ring in her belongings.  Can you please help me find our family crest.
Respectfully, Tammy Adams
