The Chronicon S. Huberti Andaginensis records that “Godefridus” [probably identified as Godefroi IV [de Boulogne/Bouillon] Duke of Lower Lotharingia] captured "Theodericum comitem qui filius Gerardi Flamensis" who died after six months in captivity and whose burial was planned at Köln St. Gereon but who was finally buried “in ecclesia beati Huberti”, dated to 1082 from the context. [Kurth indicates that “il est probablement question de lui” in the following charter (“comes Theodericus”). "Ermengardis avorum meorum predecessione ammonita" donated property at "Wereme...in Berlenges et in Jalmin...apud Lon...in Rumines...in Curinge..." to Liège Saint-Lambert by charter dated 5 Feb 1079, witnessed by "Reinerus advocatus, comes Adelbertus, Heinricus, Warnerus, filius eius Heinricus, comes Cono, Rodulphus frater, comes Otto, comes Arnulphus, Godefridus et Arnulphus, Godescalcus de Cennaco...", reserving rights of “comes Theodericus super ea advocaturam”, all confirmed by “comes Heinricus”.
The name of Dietrich's wife is not known. 1
