There were several citations of Frankish soldiers or minor nobles named Huon in Evan Connell's Crusades chronicle, "Deus Lo Volt!", which I mentioned some months ago here I was reading and have since settled into one chapter at a time. (The frightful barbarism and carnage of the period must be taken in bite-size chunks or not at all. No CNN then, and it was probably a good thing!)
Also encountered the name in one of the early French tales of Charlemagne -- don't recall which one.
The French name links you provided here, altho without meanings, are very interesting. Kate Monk mentions that the names in her list differ from the more Latin names in Languedoc (southern France), but I also noted in Evan Connell's book that the Provencal (Languedoc) names he cited were often interesting variants of both Monk's name list and the more normal run of medieval French (Languedoui?)names we're accustomed to.
I'm still trying to decide which it was more horrifying to be in 12th-century France, a Jew or an Albigensian...
