He’s the eighth B. de Raby.

Neville was a supporter of King Henry IV who endowed him with the honour and lordship of Richmond for life. The Neville family were natural rivals of the Percy family. In 1403, the power of the Percy's had fallen at the Battle of Shrewsbury. Both marches had been in their hands, but the west marches was now assigned to Neville, who's influence in the east was also paramount. Neville had prevented Henry Percy, 1st Earl of Northumberland, from marching to reinforce his son, Henry Hotspur Percy, before embarking on a new revolt to secure his enemy, Northumberland. In May 1403, while the Percy's were in revolt with Thomas de Mowbray, 4th Earl of Norfolk, and Archbishop Scrope, Neville met them at Skipton Moor, near York, and suggested a parley between the leaders. Scrope and Mowbray were seized after Mowbray let his followers disperse and handed over to Northumberland at Pontefract Castle. It is believed by some historians that the two had voluntarily surrendered. If Neville had betrayed them, he certainly shared no part in their execution.
