Battle of Towton

I'm presently researching the Battle of Towton. On the files page I've
posted an Exel file listing details of all the people involved in the
campaign, to the best of my present knowledge.
If anyone can add to or correct the list I'd be grateful for any new
information.
Many sources (including some modern ones) are confused as to who
actually participated. For example some list the Duke of Buckingham
and the Earl of Shrewsbury as having fought in the battle, but they
were surely too young.
Any other files relating to the battle can be posted in the folder.
