BERENGAR [I] von Sulzbach, son of GEBHARD [II] Graf von Sulzbach & his wife Irmgard von Rott ([1080]-3 Dec [1125], bur Kastl). Wegener quotes no source which proves that Graf Berengar was the son of Graf Gebhard [II][1490], although this affiliation is probable. Graf von Sulzbach. The documents dated Feb 1111 relating to the coronation of Heinrich V King of Germany as emperor name "Fridericum filium sororis suæ, marchionem Engilbertum, marchionem Thiebaldus, comitem Hermannum, Fridericum palatinum comitem de Saxonia, Berlingarium de Bavaria, Godefridum comitem, Fridericum Saxonum, Albertum cancellarium, Cononem fratri Berengarii, Sigebot de Bavaria, Henricum ducem Carinthie, Bertoldum filium ducis Bertoldi" as the emperor's guarantors, in a later passage "Berlingarium de Bavaria" signing as "Beringarius comes de Bavaria"[1491]. "Comes Peringarius" donated "ecclesiam…Etindorf" to Bamburg by charter dated to [1120][1492]. Founder of Berchtesgaden and Baumburg. Co-founder of Kloster Kastl. The Concordat of Worms dated 23 Sep 1122 is subscribed by "…Berlingarius comes"[1493]. A document of Lothar King of Germany dated Aug 1125 names "…B comes de Sulzbach…"[1494]. The necrology of Baumburg records the death "III Non Dec" of "Perengarius com de Sulzpach fundator"[1495]. The necrology of Salzburg St Rudpert records the death "III Non Dec" of "Berengarius com"[1496].
m firstly ([1100]) as her third husband, ADELHEID von Lechsgemünd, widow firstly of MARKWARD Graf im Chiemgau [Sieghardinger] and secondly of ULRICH Graf von Passau, daughter of KUNO von Lechsgemünd & his wife Mechtild von Horburg [Achalm] (-24 Feb [1108]). The Fundatio Monasterii Baumburgensis names "in Bawarie provincial comes…Cuno…filiam Adilheit" as founder of Kloster Baumburg, naming her first husband "comes Marcohardus de castro…Marcarstain", her second husband "comes Udalricus de Pactavia" and her third husband "Berngero comiti de Sulzphach"[1497]. The necrology of Baumburg records the death "VI Kal Mar" of "Alheidis com fundatrix"[1498].
m secondly ADELHEID von Wolfratshausen, daughter of OTTO II Graf von Wolfratshausen & his wife Justizia --- (-11/12 Jan 1126, bur Kastl). Wegener cites the Kastler Reimchronik which names Adelheid von Wolfratshausen as the wife of Graf Berengar[1499]. Some indirect corroboration of a connection between the Grafen von Sulzbach and the Grafen von Wolfratshausen is found in the De Fundatoribus Monasterii Diessenses which inaccurately names "Richentzam Lotharii imperatoris uxorem et Mariam imperatricem Grecorum" as daughters of "Ottonis de Wolfarthausen"[1500]. Some creative interpretation of this text is required: firstly, that it confuses the wife of Emperor Lothar and his successor Konrad III King of Germany (the latter being married to a daughter of Berengar Graf von Sulzbach); secondly, that "Mariam" is an error for "Bertam" the name of another daughter of Berengar Graf von Sulzbach who was married to Emperor Manuel I; and thirdly, that it omits reference to the intervening generation of the daughter of Graf Otto. "Cometissa…Adilheit de Sulzbach" donated property to Bamburg by charter dated to [1120][1501]. The necrology of Tegernsee records the death "II Id Jan" of "Alhaidis comitissa de Sulzpach"[1502], the Liber Oblationum recording the death "III Id Jan" of "Alhaidis com de Sultzbach sor nra" and her burial "in capitolio nostro"[1503]. The necrology of Salzburg St Rudpert records the death "III Id Jan" of "Adelheit com"[1504].
