| Notes |
- Gertud von Northeim was the daughter of Heinrich 'der Fette' von Northeim, and his wife Gertrud von Braunschweig.[1]
Her birth date is never mentioned in any of the early sources, but as she had three children with her first husband who was killed on 3 September 1113, and that marriages tended to be when women were still in their teens, a birth date of about 1095 seems reasonable.
First marriage and children
Grafin (Countess) Gertrud von Northeim married firstly, before 27 August 1111, Siegfried von Ballenstedt, Graf von Orlamund and Pfalzgraf von Lothringen.
They had three children;
Siegfried II, succeeded his father as Graf von Orlamunde, died 19 March 1124;
Wilhelm, succeeded his brother as Graf von Orlamunde;
Adela, married as his second wife; Konrad, Graf von Peilstein.
Grafin (Countess) Gertrud von Northeim lost her first husband when Siegfried was killed in battle on 3 September 1113.
Second marriage and children
Grafin (Countess) Gertrud von Northeim married secondly circa 1115, Otto von Salm, later Graf von Rheineck and Bentheim, Pfalzgraf von Lothringen.
Grafin (Countess) Gertrud von Northeim also had three children with Otto von Salm:
Otto von Rheineck;
Sophie von Rheineck, married Dirk VI, Count of Holland;
Beatrix von Rheineck, married Wilbrand, Graf von Loccum und Hallermund.
Grafin (Countess) Gertrud von Northeim lost her husband in 1150 when Otto von Salm was murdered by strangulation. in 1150, before 12 November.
Later life
Grafin (Countess) Gertrud von Northeim is referred to as Gertrude von Bentheim (Gertrude comitissa Benthemiensi and Gertrudis de Benthem) in two charters dated to 1150-1154 and 1154.[1]
This appears to be the last mention of Gertud and she died sometime between 1154 and 1165 when she is definitely referred to as deceased.
Death
Grafin (Countess) Gertrud von Northeim is buried at Loccum according to the Medieval Lands Database.
Research Notes
Bayern (Bavaria) is inappropriate as the LNAB for this family. Gertrud's grandfather Otto von Northeim was appointed Duke of Bavaria in 1061 but was deprived of this territory in 1070 and neither he nor any of his family were ever to regain Bavaria.
