I think we've got an improper merge here - the 1st Earl of Worcester and the 4th Earl of Warwick? These are two different people!
I didn't know there was any attempt to merge these two gents. They are, indeed, two separate people. But, which two?
There seem to have been a number of people who took the title, 4th Earl of Warwick.
Thomas Percy, 1st Earl of Worcester (1343 – 23 July 1403) This is clear.
But which of these guys has been merged with Percy?
Waleran de Newburgh 4th Earl of Warwick (1184-1203);
Thomas Beauchamp, 4th Earl of Warwick
George Guy Greville, 4th Earl of Warwick
Now my curiosity is piqued.
Do not merge this page with Person:Waleran de Beaumont, 4th Earl of Warwick (1).
I think I've extracted everything obviously related to the 4th Earl, and made things consistent with WP over there. Perhaps the other "4th" earls you note, are later creations? --Jrm03063 12:30, 10 June 2009 (EDT)
