"The monument to George Heald [in Horncastle Church, Lincolnshire] says George Heald armigery, that is he was able to bear arms, he had his own coat of arms. His coat of arms is on the left; on the other is the griffin, which was of his wife who was one of the Traffords...
"Interestingly I checked on the coats of arms and she was allowed coats of arms because she was a member of the Trafford family. I looked him up but I couldn't find him so I wrote to Garter King of Arms who was the chief advisor for the Monumental Brass Society. I described the arms, and he wrote back and said, 'No these are spurious, the man who had those had no right to bear arms', and yet it says armigery, he was entitled to bear arms. "
