I saw on a name board that someone said it has "questionable legitimacy". I know it happens to be the French word for April but I always thought it was a form of Eoforhild like this site says, or is this Averill? To me, it's an English name. I have an Avril in my family tree going back 160 years but I would have to recheck its spelling (?) It appears it has lots of use in England over the last 200 years. Still, not "legit" then?
