Dietbirg (Theotberga) von Thurgau

same as Thietburg 'Dietprich' but here in wrong position reading below:

Please see Discussion suggesting that Dietburg's correct father must be Burkhard:

Everard van Dijk says: There is a file on Google with the title (Adalbert "dem Erlauchte" - Mittelalter) This file is part of: www.manfred-hiebl.de system. Childern 1. Buchard 855/60-911 2. Adalbert III +911 hingerichtet 3. Dietbirg (Theotberga) OO Hucbald graf von Dillingen -909. 4. Manegold. Many times I have seen in the past that the childern are not complete. Important no name of his wive but NN. Important as well it is from the www.genealogie-mittelalter.de Literatur: not clear while the text is very long.

Justin Swanström C says :Dietbirg (Theotberga) is controversial. Charles Cawley at Medlands calls her Dietpirch (another form of Dietbirg). He says:

DIETPIRCH (-17 or 22 Mar after 923, bur Wittislingen). Dietpirch is named as wife of Hupald in the Vita S. Oudalrici[72]. Herimannus names "Dietpirch" as daughter of "Burchardus dux" and wife of "Hartmannus comes"[73]. The Vita b. Hucbaldi names "Theobergam, filiam Burcardi ducis Sueviæ de genere Veringarum" as wife of "Hucbaldus", specifying that she brought Dillingen to her husband[74]. The necrology of Neresheim records the death "XVI Kal Apr" of "Dietpirga com mater s Udalrici"[75]. The necrology of Ottenburen records the death "XI Kal Apr" of "Dietpirc mater s Uodalrici ep"[76]. m HUPOLD, son of HARTMANN & his wife --- (-16 Jul [909], bur Wittislingen). "Hupaldus" is shown as son of "Hartmannus comes" and husband of "Dietpirch". http://fmg.ac/Projects/MedLands/SWABIA.htm#DietpirchMHupold

So, daughter of Burkhard II not Adalbert II.

Manfred Heibl thinks the wife of Hucbald was Dietbirg, daughter of Adalbert.

The sources cited by Cawley seem to be very clear. The correct father must be Burkhard unless there is a dating problem to disprove it.

More from the "Vita beatus Hucbaldi" here. See the footnote at the bottom of page 20: Annales Babenbergenses, Ensdorfenses, Augustani Minores (1852). https://books.google.com/books?id=jzNhAAAAcAAJ&pg=PA20&lpg=...
