The coat of arms and heraldry for the Fay name is best shared here with a few articles that I discovered. Many countries claim origin for the name. Researchers have decided that there are actually two distinct divisions for the Fay name, the French Branch and the Irish Branch. I believe that the research previously done and my DNA results indicate our Fay line is neither. We are from either Scotland, England, Wales or Germany. The French heraldry uses a dragon and the Irish heraldry uses a boar. Below are some links to information about the Coat of Arms and Heraldry.
