OK, I HAVE to say one more thing.
The WHOLE discussion on whether the Harden baron would be appropriate in wearing an eagle feather has NOTHING to do with the origin of Harding. I was just pointing one avenue for him to look.

As for Mark Harden, he is morally and appropriate to wear the feathers, as is his "baron bailey" (a friend of mine, commonly nicknamed "Baron MacBubba"). As Harden WORKS with the person who handles heraldic matters for the Scottish world, he would have to be AN IDIOT to do it WRONG. Harden is NOT, so I don't question it!
(His OWN views on heraldry: http://www.houseofharden.com/cowdenk...raldryhome.htm )
He wore one in Greenville walking NEXT TO Romilly Squire (Heraldic Artist to the Lyon Courtand) ON STAGE DURING a presentation of heraldic honors to the Sinclair chief!

Therefore, I ASSUME he has ALL moral, legal, and all legit RIGHTS to wear feathers!
