Sir William Bonville, K.G.

I keep seeing references to him having been knighted about or before 1417 but I recently discovered a document in the national archives that indicates he (or someone with a similar name)was in the retinue of the Duke of Clarence in the 1415 expedition to France.He is listed as William Bonvyl as a man at arms and captain under the command of Henry V.When I looked up the document code it was for the muster roll of the Duke of Clarence's retinue for 1415 which leads me to believe that he may have been at Agincourt and perhaps knighted for service there.It is generally believed that he was particularly closely connected to the Duke of Clarence later so i think it must be him.Has anyone else seen this?I have ordered a copy of the document and will report back what I learn if anyone else is interested.
