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, 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.

Hi Angelina - thank you - yes I've been using that extensively.

Milon IV de Tonnerre and Milon III de Tonnerre

The wife of the topic profile - at the moment called Gui de Tonnerre, comte de Tonnerre -Gui I, count of Tonnerre
is named Adèle de Salins - Adèle de Narbonne, dame de Salins ,
and they are both given as the parents of Windemodis de Salins - Wandalmodis, dame de Salins

Constance Bouchard in Sword, Miter, and Cloister (1987) has a theory that it is possible to identify Adela, wife of Milo, with the daughter of Humbert I Seigneur de Salins who was the mother of Wandelmodis and grandmother of Engelbert Comte de Brienne.

But Cawley cites a charter dated 950 where she names her parents as "Landrici patris mei, Emme matris mei"

It's possible that the positioning of Windemodis de Salins profile Wandalmodis, dame de Salins is one of original mismerges years ago.

Ahhh - found it :-)

https://fmg.ac/Projects/MedLands/burgkcounty.htm#HumbertIISalinsdie...

Adèle de Salins - the mother of a WANDALMODIS son -
is supposed to be positioned as the daughter of Humbert I de Mâcon, Seigneur de Salins

with a possible sister called WANDALMODIS, who married BERARD Seigneur de Beaujeu.

This profile is a right mash up of all of that

Wikipedia has a version that suggests that Hubert's wife - also called Wandelmodis - was a daughter of Gui d'Escuens. This may be the source of the Guy mismerge on Geni

https://en.wikipedia.org/wiki/Humbert_I_of_Salins

However, Wikipedia's citation Jean-Baptiste Guillaume (1757). Histoire généalogique des sires de Salins au comté de Bourgogne: avec des notes historiques et généalogiques sur l'ancienne noblesse de cette province. Jean-Antoine Vieille. pp. 7–9.
https://archive.org/details/bub_gb_NjcVAAAAQAAJ/page/n21/mode/2up?q... includes no references to any Wandelmodises that I can see, let alone a daughter of Gui d'Escuens
(It may be that my French is the problem, though.)

We do, however, have an UNSOURCED :-/ profile for Gui, comte d'Escuens as a father of Windelmode d'Escuens - so I'm going to move this family over there.

Having spent a couple of weeks exploring all options, I'm going to assumre that the unsourced profile for Gui I, count of Tonnerre has been FUBARed and is best simply disconnected rather than being forced onto yet another profile on the tree.

I will try and locate the correct position for what was his father: Rénaud I, comte de Tonnerre

... who is positioned as the daughter of Adéle d'Auxerre

There seem to be good reasons why these profiles are not sourced > there are NO sources :-/

Rénaud I, comte de Tonnerre seems to have been yolked to a brother-in-law Rénaud I, vicomte d'Auxerre by the possibly imaginary relationship of his supposed wife, Adéle d'Auxerre

My best guess is that this is an attempt to track the entry of Bar-sur-Seine into the inheritence of the Counts of Tonnerre... I think it's relying on or connected to this list on wikipedia https://fr.wikipedia.org/wiki/Ch%C3%A2teau_de_Bar-sur-Seine that is citing

Ernest Petit , History of the Dukes of Burgundy of the Capetian race with unpublished documents and supporting documents , vol. II, Paris, Lechevalier,1888, “Genealogy of the first counts of Tonnerre, unpublished documents from the 10th century to serve history...and of the previously unknown counts of Bar-sur-Seine”, p. 419-442, read online [ https://gallica.bnf.fr/ark:/12148/bpt6k111725f/f443] on Gallica

And as all of these are in the diocese of Langres:

The diocese of Langres , founded at the end of the 2nd century , was one of the largest and most prestigious in France under the Ancien Régime . Its incumbents, who were dukes and peers of France , took part in the coronation ceremony of the kings of France, where they carried the sceptre .
In 1730, the diocese of Langres included the regions of Tonnerre , Bar-sur-Seine , Bar-sur-Aube , Chaumont , Châtillon-sur-Seine and Dijon , ..
It was neighboring the diocese of Toul to the north (a diocese which came under the Holy Roman Empire and only became French in 1648, and Lorraine in 1766), that of Besançon to the southeast ( Franche-Comté also came under the Empire and was only attached to the crown in 1678), and that of Chalon(-sur-Saône) and Autun to the southwest which came under the Duke of Burgundy in conflict with France until the reign of Louis XI .https://fr.wikipedia.org/wiki/Liste_des_%C3%A9v%C3%AAques_de_Langres

so perhaps another way into investigating the Tonnerre /Bar-sur-Seine connection might be by looking at the two de Tonnerre cousins who became bishops of Langres:

https://fr.wikipedia.org/wiki/Liste_des_%C3%A9v%C3%AAques_de_Langres

• Hardouin de Tonnerre, Bishop of Langres
• Hugues Rainard de Tonnerre, Comte de Tonnerre & de Bar-sur-Seine. Bishop of Langres
