Who was the first of the Anglo-Norman kings to bear an English name? Which one was the first to speak fluent English? When was it and why did it happen?

The king with the Saxon name Edward I was born in 1239 and ruled in 1272-1307. His great-great-grandson Henry IV (Shakespearean hero Henry Bolingbroke) ruled from 1399. He was the first to speak English fluently, because during his childhood the Hundred Years War was already unsuccessful for England and the French language became unpopular among the English nobility.
