These are my own ancestors, hence my interest. I researched the date of BOTH their deaths on the same day and that was about the time the Northern Rebels had celebrated Catholic mass in Durham and then marched on York. Led by Charles Neville, 6th Earl of Westmorland.. From Durham, the rebels marched south to Bramham Moor, where they halted in the summer of 1569.. Queen Elizabeth struggled to raise forces sufficient to confront them. But, hearing of a large force being raised by the Earl of Sussex, the rebels finally abandoned plans to besiege York, and captured Barnard Castle instead. They proceeded to Clifford Moor, but found little popular support. Sussex marched out from York on 13 December 1569 with 7,000 men against the rebels' 4,600, and was followed by 12,000 men under Baron Clinton. The Rebel Earls retreated northward and finally dispersed their forces, fleeing into Scotland. Bramham Moor, where the Rebels camped is only a stone's throw from Harewood, (where William and his wife lived). It is undocumented, but I find it highly likely that as they were probably reformist, and high profile in Harewood they would have paid the ultimate price from the retreating Catholic rebels.
