d. 987, count of Anjou.
Rodulfus Glaber [ii, 3 (pp. 30-1)] states that Conan married a sister of count Foulques of Anjou, the Chronicle of S. Florent says that Geoffrey was son of Conan by a sister of Foulques [Lobineau (1707), 2: 85], and the Angevin genealogical collection states that Judith, wife of Richard of Normandy, was the daughter of Conan by his wife Ermengarde, daughter of Geoffroy of Anjou [Poupardin (1900), 208].
Mother: Adèle de Troyes, daughter of Robert I, count of Troyes.
Chronologically, Ermengarde must be a daughter of Geoffroy's first marriage.
Conan I, d. 27 June 992, count of Rennes.
See the page of Conan I for a detailed discussion of his children, including some doubtful ones not listed here. Both Geoffroy and Judith are directly documented as Ermengarde's children.
Geoffroy I, d. 1008, duke of Brittany.
The Cronicle of S. Florent says that Geoffrey was son of Conan by a sister of Foulques [Lobineau (1707), 2: 85].
Judith, m. Richard
II, duke of Normandy.
The Angevin genealogical collection states that Judith, wife of Richard of Normandy, was the daughter of Conan by his wife Ermengarde, daughter of Geoffroy of Anjou [Poupardin (1900), 208].
The following children of Conan are not directly documented as children of Ermengarde, but they could be her children. However, if the statement that Judicaël became bishop during the life of his father is correct [Cart. Redon, 309], placing him as a son of Ermengarde would be a tight chronological fit.
Judicaël, bishop of Vannes.
Catuallon, abbot of Redon.
Ermengarde d'Anjou, wife of Conan I de Rennes, is combined by some authors with her sister,
Gerberge d'Anjou, wife of Guillaume IV, count of Angoulême, into a single individual,
Ermengarde/Gerberge, supposedly m. (1) Conan I; (2) Guillaume IV.
The only reasons given for this identification are that the Saint-Aubin genealogies only give Geoffroy Grisegonelle one daughter (Ermengarde), and that double names were common in this family [Bachrach (1984), 117, n. 35]. The first point is not a strong one, and the second point is debatable, since the other examples of "double names" given by Bachrach involve the use of "Blanche" (Blanca, "white") as a surname [see Settipani (1997), 251], similar to the use of epithets like "Grisegonelle" and "Nerra" among the men. In any case, in the absence of evidence connecting Ermengarde and Gerberge, there is no good reason to interpret the evidence in any way other than the obvious one: that they were two different daughters with two different names.
