Cte Milon IV DE TONNERRE
- Born: Between 950 and 965, Tonnerre, Yonne, Bourgogne, France
- Died: Abt 1002
Died in 1002 or after.
The parentage of Milo [IV] is not known. There are three possibilities. Firstly, he could have been the same person as Milo [III] [who was father of Milo V]. This is not an ideal fit. Milo [IV] does not name Milo and Guy among his “carissimorum filiorum” in his charter dated to [992/1005].
The addition of “carissimorum” suggests that the three sons named in the document were his only children, as it is difficult to imagine how he could have had other children whom he did not consider “carissimorum”. One possibility is that Milo [V] and Guy would have been born after the date of the charter. However, the document strongly suggests that it was written with the donor’s death in mind as he requests that his own and his wife’s anniversaries be remembered, although it is of course not impossible that he recovered from the illness from which he was suffering and had more children. Secondly, Milo [IV] could have been an older son of Milo [II] who succeeded his father in the county. The birth date ranges for Milo [IV] and for Guy, known son of Milo [II], allow for this possibility. Thirdly, he could have been the son of an otherwise unknown older son of Milo [II] who succeeded his paternal grandfather in the county. The birth date ranges are not incompatible with this possibility either, assuming that Milo [II]’s son Guy was born early in the date range shown for him above, while Milo [IV] was born late in his birth date range. As can be seen, no factor points conclusively to one of these possibilities being correct. It is preferable therefore to avoid further speculation and show his parentage as unknown, although it should be emphasised that the suggested birth date ranges assigned to the various members of this family are speculative and that the conclusions could be different if they were incorrect.
Comte de Tonnerre. "Milo comes, Lambertus, Richardus, Albericus, Archanradus, Calo, Girvardus, Raynardus comes, Erembertus, Ormundus, Widricus, Milo, Achardus, Odo, Raynardus" witnessed the charter dated to  under which “Umbertus…et mee conjugis…Giberge” donated property "in villa…Curtis-Secreta…in comitatu Tornodorense" to Saint-Michel de Tonnerre.
"…Raynardi comitis…Milonis comitis, Aremberti…" subscribed a charter dated to  which deals with the property at Coussegré. “Milo comes Tornodorensis castri” donated property "in villa…Curtis-Secreta" to the monastery of Saint-Michel, with the consent of “coniugis mee Ermengarde et carissimorum filiorum meorum Achardi, Rainardi et Alberici”, by charter dated to [992/1005]. The charter appears to have been written with his own death in mind as he requests the anniversaries of his own and his wife’s deaths to be remembered. 1
Milo(n) married Ermengarde. (Ermengarde died after 1018.)
