Minerva McGonagall's wand

Minerva McGonagall's wand is not mentioned often in the series. Her wand probably chose her as McGonagall has done great magic with it. This includes complex Transfiguration, expert duelling, defensive spells and a lot more. This would not be possible if the Wand had not chosen Minerva. She probably received it from Ollivander at the age of eleven like most witches and Wizards in Britain.
