In 2008, George Bush signed a Presidential Proclamation making April 6th National Tartan Day to celebrate Scottish history and the achievements of people of Scottish descent. The Greer family descends from the MacGregor clan. Though there are other tartans associated with this clan, the current chieftain has restricted the wearing of the rest of the tartans and has declared that descendants wear either the MacGregor Red & Black (also known as the "Rob Roy" MacGregor tartan) or the MacGregor Red & Green.
