Took out the official and legal title stuff, because that concept just didn't exist in the 10th century, to the best of my knowledge. There was no administrative mechanism for "official and legal" titles -- births were not regularly registered, names changed as family possessions changed, etc. For most leading families in what had been Francia (and remember, Louis the Child died in 911, and there were still Carolingian family members around after his death), there were very few regularized titles -- especially titles bound to specific chunks of land! If somebody can show me real documentation (from the time, and not some later document based on an assumption) for this, I'll put this back.
