Father:
Heribert, d. 992, count in
Kinziggau.
This parentage was convincingly argued by Schenk zu Schweinsberg
[Schenk zu Schweinsberg (1904)]. The main basis is the notice
which describes the consanguinity between Otto von Hammerstein
(son of Heribert) and his wife Ermengarde ["Item ex alia
parte: Godefridus et Gerbirhc nepos et neptis. Godefridus genuit
Irmingardam. Gerbirhc genuit Imizam. Imiza genuit Ottonem.."
[MGH Const. I 639; Schenk zu Schweinsberg (1904), 351;
Hlawitschka (1969), 49; here, in the first sentence, "nepos
et neptis" is to be interpreted that Godefroid and
Gerberge had a common grandparent, i.e., that they were first
cousins]. Noting that Imiza was a shortened form of the name
Ermentrude/Irmintrud, and that Frédéric's daughter
Imiza/Ermentrude, wife of Welf II, was stated to be "de
gente Salica de castro Glizberch" ["Guelfo
supra nominatus, Roudolfi huius filius, uxorem duxit de gente
Salica de castro Glizberch, Imizam nomine, sororem Heinrici ducis
Noricorum et Friderici ducis Lotharingiorum et Adilberonis
episcopi Metensis", Historia Welforum Weingartensis,
MGH SS 21: 460; similarly in Genealogia Welforum, MGH SS
13: 734]. Schenk zu Schweinsberg identified Gerberga and her
daughter Imiza in the Hammerstein notice with the Gerberga and
her daughter Ermentrude who appear in the life of abbess Adelheid
of Vilich (see below). This identification is now widely
accepted.
Mother:
Ermentrude (Imiza), daughter of Megingoz and Gerberge.
In the life of abbess Adelheid, daughter of Megingoz and
Gerberge, Adelheid's sister Ermentrude is stated to have been the
grandmother (avia) of dukes Henri/Heinrich and
Frédéric and bishop Adalbero ["Ex quibus una nomine
Irminthrudis avia erat Henrici magnifici ducis et Adhelberonis
Metensis episcopi, Friderici ducis fratrumque suorum, magnorum
scilicet huius temporis virorum." Vita
Adelheidis Abbatissae Vilicensis, c. 3, MGH SS 15: 757].
Since Frédéric's mother is known to have been named Hedwig (see
the page of Frédéric's father Sigefroid), this identifies
Ermentrude as Frédéric's mother-in-law, but without identifying
the name of Frédéric's wife. Note that this source gives direct
proof only for the identity of the mother-in-law of Frédéric,
and does not identify Ermentrude's husband, which involves less
direct evidence. (See also below in the Commentary section.)
Spouse:
Frédéric, d. 6 October 1019, count; advocate of
Stavelot-Malmedy.
See above.
Children:
As mentioned above, Henri/Heinrich, Frédéric,
and Adalbero are documented as grandchildren of
Ermentrude. See the page of their father Frédéric for documentation of the remaining
children.
Ermentrude (Imiza), d. 2 August, year unknown; m. (perhaps ca. 1015), Welf II, count of Altdorf.
Henri/Heinrich, d. 14 Oct. 1047, advocate of Echternach and Saint-Maximin; count in Moselgau and Bidgau; duke of Bavaria, 1042-7.
Frédéric, d. 1065, advocate of Stavelot-Malmédy; duke of Lower Lorraine 1046-1065; m. (1) Gerberge, daughter of Eustache I, count of Boulogne; m. (2) Ide (or Raelendis), who later m. (2) Albert, count of Namur.
Giselbert, d. 14 August 1056×9, advocate of Saint-Maximin, count of Luxemburg, count of Salm.
Adalbero III, d. 13 Nov. 1072, bishop of Metz, 1046-1072.
Thierry/Dietrich, fl. 1036, 1056.
Hermann, of Gleiberg, living 1045, 1056.
Oda, nun in Reinersberg, abbess at Lunéville.
Possible children:
Otgive was a daughter of either Frédéric or his brother
Giselbert, and Gisèle was a sister of Otgive, whose parentage is
discussed in detail on her page.
Obviously, these two are to be placed as children of our unnamed
countess only if Otgive and Gisèle were children of Frédéric.
Otgive, m. Baldwin IV, count of Flanders.
Gisèle, d. 22 May, year unknown;
generally believed to be the same as:
Gisèle, m. Raoul, advocate of
Saint-Pierre de Gand, lord of Alost.
Falsely attributed
father: Richard,
fl. 971, count of Metz.
Prior to Schenk zu Schweinsberg's paper,
Vanderkindere had conjectured that Ermentrude's husband was count
Richard of Metz [Vanderkindere (1902), 2: 172, 179]. For count
Richard, see Chatelain (1898-1901), 13: 294-5; Hlawitschka
(1969).
