I'm not sure if this goes here, in the Clans forum, or in the Heraldry forum, so if I guessed wrongly please move. Where did clan crests come from? I'm guessing they were another 19th-century invention, but I haven't heard anything about their history. Were there Allen brothers for crests? I think they are heraldic, but where did the practice come from of wearing them on a bonnet? I believe I have read that it was post-1746. I'm just curious, I love history and like to know the history of things.
