Gui I, count of Tonnerre - Where does this fit?

I've spent the better part of 4 hrs trying to puzzle this out, Frank. It looks like a Curatorship I inherited, and without sources it appears to be impossible to figure out what the mismerge was that must have happened.

If his father is Rénaud I, comte de Tonnerre (872-96) the Comtes of Tonnerre don't even seem to have Raynard as a name enter their line before Milon IV marries Ermengarde NN, heiress de Bar-sur-Seine of the 1000s, the daughter/ descendant of a Rainard, who brings the the Bar sur Seine inheritence into the de Tonnerre line for the first time.

One of the difficulties is that we on Geni seem to be solving the fact that we cannot pinpoint how her husband - Milon IV - fits in between Milon II and his known son Milon V - by merging Milon III with Milon IV.

This is one of the options scholars have proposed - so the timelines may fit at a stretch, and it brings Raynards and Guys into the same descent lines at least, but significantly later than these dates propose; and it brings other problems too - including no obvious father Raynard- son Guy relationship in the de Tonnerre line...

so I'm going to assume that this profile and his parents are just wrong in time or in place on Geni, and we don't have enough source information to locate them in either :-/

I'll continue working on the line though.
