[Vita Adelheidis Abbatissae Vilicensis, c. 3, MGH SS 15, 757]

Mother: Gerberge, daughter of "duke" Godefroid
[Vita Adelheidis Abbatissae Vilicensis, c. 3, MGH SS 15, 757]

Spouse: Heribert, d. 992, count in Kinziggau.
[Schenk zu Schweinsberg (1904), part I: "Die Verwandtschaft des Grafen Otto von Hammerstein mit seiner Gemahlin Irmingard", pp. 351-9]. For more details, see the page of her unnamed daughter, the wife of Frédéric, advocate of Stavelot-Malmédy (often called "of Luxemburg").


MALE Gebhard [Thietmar Chron. vii, 34, MGH SS 3, 852; Annalista Saxo, MGH SS 6, 671], d. 8 November 1016 [Thietmar Chron. vii, 34, MGH SS 3, 852 (day of year: ibid., n. 23, citing V. Calend. Merseb.)], count.

MALE Otto "von Hammerstein" [Thietmar Chron. 5, 16, MGH SS 3, 797, Annalista Saxo, MGH SS 6, 650], d. prob. 1036, count in Wetterau ["... in pago Wedereiba in comitatu Ottonis situm ..." MGH DD H 2, 450 (#351)].

FEMALE NN; m. Frédéric, d. 6 October 1019, count; advocate of Stavelot-Malmédy.
In the life of Ermentrude's sister abbess Adelheid, 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.).


Supposed daughter (unproven):
FEMALE Gerberga, m. Heinrich von Schweinfurt.
This link is suggested by a passage of Thietmar of Merseberg, who gives Gerberga a brother Otto, who is otherwise unidentified, but can be plausibly identified as Otto von Hammerstein [Thietmar v, 21, MGH SS 3: 800-1]. Although unproven, this link would also fit well onomastically, since Ermentrude's mother was named Gerberge [see Brandenburg (1964), 93; Werner (1967), 476-7].

Falsely attributed marriages (conjectured by Vanderkindere):
(1) Richard
, fl. 971, count of Metz.
(2) Arnoul de Florennes
, d. before 1010.
[Vanderkindere 2: 178-9]
