The 14th century Deutsche Reimchronik of Kloster Kastel records that “Gebhardus...Sultzpach” had “ainon Suon...Grafe Bernger”.
Graf von Sulzbach. Berengar [III] must have been a child when his father died, which is consistent with the chronology of his later life. 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". “...Comes Peringer...” witnessed the charter dated 29 Sep 1108 issued by Heinrich V King of Germany for the church of Bamberg. "Comes Peringarius" donated "ecclesiam…Etindorf" to Bamburg by charter dated to [1120]. Founder of Berchtesgaden and Baumburg. Co-founder of Kloster Kastl. The Concordat of Worms dated 23 Sep 1122 is subscribed by "…Berlingarius comes". “Comes...Peringarius unacum uxore sua Adelheida ac filio Gebehardo” donated “ex hereditate matris...in villa Grettich et in Sconeberge et in Grauingadem” to Berchtesgaden by undated charter. Wegener dates this charter to early Dec 1125. A document of Lothar King of Germany dated Aug 1125 names "…B comes de Sulzbach…".
The necrology of Baumburg records the death "III Non Dec" of "Perengarius com de Sulzpach fundator". The necrology of Salzburg St Rudpert records the death "III Non Dec" of "Berengarius com". The Latin Chronicle of Kloster Kastel records the death “pridie Non Dec” 1125 of “dominus Perngerus comes de Sultzpach fundator huius ecclesie” and his burial “in monesterio Scti Petri in Kastello”. 1
