MANEGOLD (-1 May 991, bur Quedlinburg Cathedral). According to Europäische Stammtafeln, Manegold was the possible son of Burkhard [I] Graf im Zürichgau[630]. "Otto…rex" gave property "in loco Badon…in pago Ufgouue…comitatu Cuonradi comitis" to "Managoldo comiti" by charter dated 27 Aug 987[631]. m ---. The name of Manegold's wife is not known.

b) EBERHARD[IV] (-[1030/34]). According to Europäische Stammtafeln, Manegold was the possible father of Graf Eberhard [IV], Vogt of Kloster Einsiedeln and ancestor of the Grafen von Nellenburg[633]. This is certainly indicated by the charter dated 11 Mar 992 under which "Otto…rex" donated property "Saramaresheim in pago Alsaciæ ac comitatu Eberhardi comitis " to Kloster Selz after the death of "Manegoldo comiti", Manegold having started the process before he died[634].] ..EBERHARD [IV], son of [MANEGOLD Graf im Zürichgau & his wife ---] (-[1030/34]).

m (1009) HEDWIG, daughter of --- (-after 1034). The Annales Scafhusenses record the marriage in 1009 of "Ebbo comes de Nellenburc" and "consobrinam Heinrici regis Hedewigam…de curie regis"[638]. If "consobrinam" is here used in its precise sense, Hedwig would have been the daughter of one of the sisters of Gisela, daughter of Conrad I King of Upper Burgundy. According to the early 12th century Vita Eberhardi[639], the mother of Eberhard Graf von Nellenburg (son of Eberhard [IV] Graf im Zürichgau) was --- of Hungary, daughter of István I King of Hungary, although it is somewhat surprising that such a prominent figure as King István, in far off Hungary, would have married his daughter to an obscure Swiss count. If Hedwig was the daughter of King István, there is a remote possibility that she was the same daughter who supposedly married Edmund ætheling, although if this is correct she would have been much older than her second husband. This supposed Hungarian origin appears unlikely, given Hedwig’s property holding in Rheingau mentioned in the following document: “comes Eberhardus cum domina Hadewiga matre sua” founded Kloster Pfaffen-Schwabenheim bei Kreuznach with his mother’s property “im Rheingau” by charter dated 1034[640]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
Graf Eberhard [IV] & his wife had [four] children:

1. BURKHARD [II] (-killed in battle Civitate 18 Jun 1053, bur Reichenau). "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[641]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
2. MANEGOLD (-killed in battle Falkenstein, Schwarzwald 17 Aug 1030, bur Reichenau). The Annales Sangallenses name "Manegolt comes" in 1030[642]. "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[643]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
3. EBERHARD(-26 Mar [1076/79]). According to Europäische Stammtafeln, Eberhard was the son of Graf Eberhard [IV], built the castle of Nellenburg before 1050 and was ancestor of the Grafen von Nellenburg[644]. Graf im Zürichgau. “Comes Eberhardus cum domina Hadewiga matre sua” founded Kloster Pfaffen-Schwabenheim bei Kreuznach with his mother’s property “im Rheingau” by charter dated 1034[645]. "Eberhardus comes Turegie provincie" exchanged property with "Bertholdo Carinthiorum duce" by charter dated early Mar 1050, witnessed by "…Burchardus et Eberhardus et Adelbertus, filii Eberhardi comitis…"[646]. This charter is presumably misdated as Berthold did not become Duke of Carinthia until 1061, and his son Marchese in 1072. The Annales Scafhusenses record that "Eberhardus comes de Nellinburc" founded "Scafhusensem locum" in 1052[647]. "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[648]. "Heinricus…rex" granted property "in villa Kiricheim in pago Nechargovve in comitatu Eberhardi comitis" to "prefatus Eberhardus comes" by charter dated 22 Nov 1059[649]. "Heinricus…rex" granted property "duas villas Hochfeld et Suueichusen cum foresto Heiligenforst in comitatu Gerhardi comitis in pago Nortcowe" to "Eberhardo comiti" by charter dated 22 May 1065[650]. "Heinricus…rex" granted property "in pagis Cletgowe et Hegowe in comitatibus Gerungi et Lodawici comitis" to "comiti Eberhardo" by charter dated 1067[651]. m ITA, daughter of --- (-26 Feb or 2 May after 1105). The Historia Trevirensis names “ex Alamannorum prosapia oriundus patre Eberhardo comite, matre Ida” as parents of “Udo” Archibishop of Trier, adding that they founded “monasterii…Scafuse”[652]. She became a nuun at St Agnes, Schaffhausen as shown by the charter dated 1 Mar 1080 under which her son "Comes Burchardus de castello Nellenburk" confirmed donations to "monasterium sancti Salvatoris in pago Cletgouve in villa Schafhusa super litus Reni" founded by "progenitoribus meis…Eberhardo, ex religioso comite in eodem monasterio monacho…facto, et Ita…monachicam…in cella sancte Agne in eadem villa"[653]. The necrology of Zwiefalten records the death "VI Non Mai" of "Ita com de Nellinburc"[654]. Graf Eberhard & his wife had [seven] children: https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
4. IRMGARD . According to Europäische Stammtafeln[674], the wife of Werner [I] was sister of "Graf Eppo a. d. H. der Gf von Nellenburg", although the primary source on which this is based has not been identified. The Graf Eppo [Eberhard] to which this refers has not been identified, although from a chronological point of view it is likely that Irmgard was the daughter of Graf Eberhard [IV] if she was a member of this family. m WERNER [I] Vogt von Kaufungen, son of ADALBERT & his wife ---] (-killed in battle 23 Aug 1040).] https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
