  Research Notes:

His parentage is confirmed by the charter dated 29 Sep 1046 in which Milon [V] Comte de Tonnerre names some of his paternal ancestors “Milo atavus meus…Wuydo proavus meus…Milo pater meus…”... [The] chronology of this family does not favour the interpretation of "proavus" in this document in any other way than "grandfather", despite this not being strictly correct from the point of view of language. If this is correct, Guy was the father of Milon [III]. ²
