  Research Notes:

“Radulfus Oysardi filius” donated property at Creil to Saint-Leu d’Esserent, and the nuns obtained the consent of "comitem Rainaldum Claromontensem…uxor eius Clementia, filia…ipsius Margarita", by charter dated to [1119]. The dating of this document is problematic: while the presence of Marguerite suggests that she was still unmarried, the date is inconsistent with the estimated birth date of Clémence. It should be noted that Mathon dates the consent given by Comte Renaud to [1153], although he does not state why he says this. If that dating is correct, the witness would have been Renaud’s daughter Marguerite by his second marriage, although it is unclear why she would have been singled out for giving consent without her brothers and sisters.

The Vita Karoli Comitis Flandriæ names "nobilem puellam Margaretam, Reinaldi comitis Clarmontensis filiam" as wife of Count Charles, specifying that the marriage took place before his accession. The De Genere Comitum Flandrensium, Notæ Parisienses refers to (but does not name) the daughter of "comes de Claromonte" and his wife Adela, specifying that she married firstly Charles Count of Flanders, secondly "Hugo Champdaveine…comes Sancti Pauli" by whom she had "Radulfus Champdaveine et Guod Champdaveine", and thirdly "dominus Balduinus de Encra" by whom she had "domini Galteri de Helli". The Genealogiæ Scriptoris Fusniacensis refers to, but does not name, the daughter of "comes Rainaldus [de Claromonte]" & his wife Adelaide as wife of "comes Karolus Flandre". It is assumed that Marguerite was born soon after her parents' marriage as her mother was already nearly 40 years old at the time. ¹
