Hi. I realize this message may come a little late, but I too was just given an interesting gift. My aunt gave me a lead crystal glass from my late grandfather that contains our family's coat-of-arms. It contained some papers from the Sanson Institute of Heraldry.
In googling it I came across this post, but I also found something else that may be of interest to someone. There is an article in Time magazine that you should read. Here is the link:http://www.time.com/time/magazine/article/0,9171,912772-1,00...
I hope the link works. You may be sadly disappointed (as was I).
