NOBILITY? So few people on earth have the right to bear a title, but it's fun to learn that you too have some illustrious ancestor. Coat of Arms are fun too - but most people with a surname that has a Coat of Arms have no right to use it: that's just for fun too, to know that SOMEONE with your surname was ennobled. Anyone who gave up their citizenship of another country to become an American citizen also gave up their right to bear arms or carry a title. In those cases where an American got a title through marriage, it's more a courtesy to use it when addressing them here in the States.
