FRIEDRICH von Büren, son of FRIEDRICH von Büren & his wife Hildegard ([1050]-1105 before 21 Jul, bur Lorch Monastery). The Tabula consanguinitatis Friderici I regis et Adelæ reginæ (which provided the basis for their divorce) names "ducem Fridericum, qui Stophen condidit" as son of "Fridericus de Buren"[249]. "Hildegardis…cum filiis meis, Ottone…Argentinenis ecclesie episcopo Suevorumque duce Friderico, Lodewico, Walthario, Cunrado et filia mea Adalheida" made a donation to the monastery of St Fides at Schlettstadt in Alsace dated 1094, presumably just before she died[250]. The De Fundatione Monasterii Sancti Fides Sletstatensis names "Fredericus dux Alemannorum [qui fuit Friderici ducis Swevie], qui Romani imperatoris filiæ coniugo, et duo eius fratres Argentinensis episcopus Otto et Conradus"[251]. "Ottone Argentinensi…episcopo" and "fratres mei dux…Suetiæ Fridericus, Ledeuvicus et Galtharius" donated property in "Scelstat villa, in pago Alsatiæ et in comitatu Beirricheim" to the abbey of Conques by charter dated 23 Jul 1095, naming "matre…nostra fratreque nostro Conrado…defunctis"[252]. He was installed as FRIEDRICH I Duke of Swabia at Easter 1079 by Heinrich IV King of Germany. Jackman[253] speculates that his theory concerning a possible Konradiner origin of Friedrich's mother could have justified Friedrich claiming Swabia for which no other genealogical basis is found, although this begs the question of the extent to which ducal appointments in Germany were based on family relationship in the 11th century. He built the castle of Stauf near Göppingen from which the family eventually took its name[254]. The Gesta Friderici of Otto of Freising records his death "in senectate" and burial "in monasterio Laureacensi"[255]. married (betrothed Regensburg 24 Mar 1079, 1089) as her first husband, AGNES of Germany, daughter of Emperor HEINRICH III [HEINRICH IV King of Germany] & his first wife Berthe de Savoie ([Summer 1072/early 1073]-24 Sep 1143, bur Klosterneuburg). The Gesta Friderici of Otto of Freising records the marriage of "filiam unicam" of King Heinrich IV and "Fridericus dux Suevorum", naming her Agnes in a later passage[256]. In a subsequent passage, the Gesta records the second marriage of Agnes to "Leopaldo Orientali marchioni"[257]. She married secondly (1106) Leopold III "der Heilige" Markgraf of Austria. The Continuatio Claustroneoburgensis records the marriage of "Liupoldus marchio Austrie" and "Agnetem imperatoris Heinrici IV filiam", specifying that the couple had seven children who died in infancy and eleven who survived into adulthood, six sons and five daughters[258]. The marriage presumably took place early in the year if it is correct, as stated by Haverkamp, that it was arranged by Agnes's brother, the future Emperor Heinrich V, to obtain her future husband's support for his rebellion against their father[259]. The Auctarium Mellicense records that Agnes, wife of "Leopoldus marchio", gave birth to 18 children[260]. The Annales Magdeburgenses record the death in 1143 of "Agnes marchionissa mater Cuonradi regis"[261]. The necrology of Nonnberg records the death "VIII Kal Oct" of "Agnes marchionissa"[262]. The necrology of Kloster Neuburg records the death "VIII Kal Oct" of "Agnes marchionissa fundatrix h e"[263].

Duke Friedrich & his wife AGNES of Germany had [twelve] children:

• 1. [HEILIKA von Staufen (-after 1110, bur Kloster Ensdorf). According to Europäische Stammtafeln[264], the wife of Friedrich von Pettendorf was the daughter of Friedrich I Duke of Swabia, although the primary source on which this is based has not yet been identified. The Fundatio Monasterii Ensdorfensis names "Fridericum et Heylwic" as parents of "Heylice palatine", specifying that they were buried at Ensdorf[265]. m FRIEDRICH von Pettendorf, son of [266][RUOTGER von Feldheim & his wife [Eilika] von Lengenfeld] (-3 Apr 1119, bur Kloster Ensdorf).]
• 2. [BERTHA . Bühler suggests that Bertha, named in the charter quoted below, was the daughter of Friedrich I Duke of Swabia[267]. Weller is more sceptical about the connection[268]. Pope Honorius III confirmed the foundation of Kloster Elchingen by "Berta comitissa et Lenugarda filia eius illiusque marito Corrado marchione et Henrico, Octone, Theoderico et Thetone filiis eorum", confirmed by Pope Calixtus II and Pope Innocent III, by charter dated 16 Aug 1225[269]. Her husband’s name is confirmed by the Chronicon Montis Serreni which names [her daughter] "Lucardis filia Alberti nobilissimi de Suevia" as wife of "Conradus comes de Witin"[270]. married ADALBERT Graf [von Elchingen], son of ---.]

Adalbert & his wife BERTHA had one child:

• >>>a) LUITGARD (-Kloster Gerbstedt 19 Jun 1145, bur Kloster Gerbstedt). The Chronicon Montis Serreni names "Lucardis filia Alberti nobilissimi de Suevia" as wife of "Conradus comes de Witin"[271]. The Genealogica Wettinensis names "Lucardem filiam cuiusdam nobilissimi de Suevia nomine Alberti" as wife of "Conradus Misnensis et Orientalius marchio [filius Thiemonis]"[272]. “Conradus...marchio...contectalis nostra Lutgardis” donated “Torgaw super ripam fluminis Albæ”, and property donated by “felicis memorie pater meus Timo comes”, to Reinhardsbrunn by charter dated 1119 (presumably misdated, assuming that Konrad’s appointment as Markgraf is correctly dated above)[273]. The Annales Magdaburgenses record the death in 1145 of "Luthgart marchionissa"[274]. Pope Honorius III confirmed the foundation of Kloster Elchingen by "Berta comitissa et Lenugarda filia eius illiusque marito Corrado marchione et Henrico, Octone, Theoderico et Thetone filiis eorum", confirmed by Pope Calixtus II and Pope Innocent III, by charter dated 16 Aug 1225[275]. m KONRAD [I] von Wettin Markgraf von Meissen, son of THIMO Graf von Brehna & his wife Ida von Northeim ([1097/98]-Kloster Petersberg 5 Feb 1157, bur Kloster Petersberg).
• 3. FRIEDRICH von Staufen(1090-Alzey 4 or 6 Apr 1147, bur Walburg Abbey). The Tabula consanguinitatis Friderici I regis et Adelæ reginæ (which provided the basis for their divorce) names "ducem Fridericum", father of "regem Fridericum", as son of "ducem Fridericum, qui Stophen condidit" and "filia regis Heinrici"[276]. He succeeded his father as FRIEDRICH II "der Einäugige" Duke of Swabia in 1105. Regent of Germany 1116. His maternal uncle Emperor Heinrich V considered him as his successor and bequeathed him the Salian dynasty's family properties to increase his personal prestige[277], but on the Emperor's death in 1125 Friedrich was passed over as candidate for the German throne in favour of Lothar von Süpplingenburg Duke of Saxony whom the German nobility saw as less of a dynastic threat. After refusing to hand over his inherited crown lands to the new king, Duke Friedrich was outlawed[278]. Friedrich eventually submitted to Emperor Lothar in 1135 with his brother. He agreed to transfer the crown lands, but was allowed to remain as Duke of Swabia[279]. "Dux Fridericus…" witnessed a charter dated 25 Jul 1139 under which Adalbert [II] Archbishop of Mainz confirmed his predecessor's grants to Kloster Jechaburg[280]. The Gesta Friderici of Otto of Freising records the death of Duke Friedrich and his burial "in monasterio sanctæ Waltpurge…in terminis Alsatiæ sito"[281].

The Urspergensium Chronicon refers to the second wife of "Friedrich I pater ipsius" as "de genere comitum…Zwainbrug et de Sarbrug"[285]. The Gesta Friderici of Otto of Freising records the marriage of "Fridericus dux, mortua uxore sua Iuditha" and "Friderici comitis de Sarbruch, fratris Alberti episcopi, filiam Agnetem"[286].

The Gesta Friderici of Otto of Freising names "Fridericum…et Iuditham" as the two children of Friedrich Duke of Swabia & his first wife, and Judith's marriage to "Matthaeo Lotharingiorum duci"[290]. The Genealogica ex Stirpe Sancti Arnulfi refers to the wife of "Matheum ducem" as "sorore Friderici imperatoris"[291].

Duke Friedrich II & his second wife had three children:

• c) JUTTA [Claricia] von Staufen ([1135]-7 Jul 1191, bur Reinhardsbrunn). The Gesta Friderici of Otto of Freising names "Conradum, qui palatinus comes Rheni…et Clariciam, Ludewici Thuringiæ comitis uxorem" as the two children of Duke Friedrich & his second wife[295]. The Urspergensium Chronicon refers to (but does not name) the daughter of "Friedrich I pater ipsius" & his second wife as the wife of "lantgravius de Thuringia"[296].

The document dated 17 Sep 1156 established the duchy of Austria is witnessed by "…Conradus frater imperatoris…"[302]. He was appointed KONRAD Pfalzgraf [von Lothringen] in 1156, but appears to have held jurisdiction in a territory in the Rhineland unlike his predecessors. As he appears to have had no connection with Lotharingia, it is more appropriate to consider him as Pfalzgraf bei Rhein. Vogt of Worms cathedral. Vogt of Lorsch.

Duke Friedrich II had one illegitimate son by an unknown mistress:
