Clémence de Sable

Her parentage is erroneously given by many secondary sources. She is known to have been a sister of Juhel de Mayenne, but the generation is not clear. Cawley and van de Pas both identify Clémence de Mayenne as the daughter of Geoffroi II, seigneur of Mayenne (died 1169), by his 2nd wife, Isabel of Meulen. Douglas Richardson has shown the impossibility of this filiation, and demonstrated that she must have been a daughter of child of Geoffroi II's 1st wife, Constance of Brittany.

The primary source which confirms her parentage has not yet been identified. Her two marriages are confirmed by the undated charter by which her son "Mauritius dominus Credoni" confirmed the donation by "Constantia soror mea" of revenue set by "dominus Juhellus frater meus" at "apud Harperiam" to the abbey of Clarei, by undated charter, witnessed by "…domina Isabel matre mea, domina Gervasia…"[756].

Geoffroy and his [first][763] wife had one child: {should probably read 'two children'}

a) MATHILDE de Mayenne .

The primary source which confirms her first marriage has not yet been identified.

Her parentage is confirmed by the charter dated 1205 under which her daughter "Margarita domina Sabolii" confirmed donations to Fontaine-Daniel by "avunculi mei domini Juhelli de Meduana"[768]. Douglas Richardson has pointed out that Clémence must have been her father´s daughter by his first marriage, otherwise her granddaughter Jeanne des Roches (daughter of Clémence´s daughter Marguerite de Sablé) would have married her great-uncle (Amaury [I] Sire de Craon, son of Isabelle de Meulan, second wife of Clémence´s father by her second marriage)[769].
