The House of Bibra (German: [ˈbiːbʁa]) was one of the leading Uradel (ancient noble) families in Franconia (northern part of Bavaria) and present day Thuringia from the mid-15th century to about 1600.
Later on the family rose from Reichsritter (Imperial Knights) to Reichsfreiherr (Barons of the Holy Roman Empire).
The earliest references to the family include a document of Bishop Otto of Bamberg from the year 1119 of a Rupertus de Bibra.
The lawsuit (Reichskammergericht) was eventually settled with the family receiving all the properties except Burgwallbach but without income during the suit.
For the last four centuries the family has divided itself between two Branches named after the two brothers whom all living Bibra descend: Valentine (1560–1595) and Bernhard (1562–1609).
Within each branch, the family has divided further in Lines centered on castles and a manor house (Gleicherwiesen).
Friedrich Gotthelf (1736-1813, Brennhausen line) claimed office in 1783 (five years early) even though Prince Bishop Heinrich (1711-1788) was older but was unable to fulfill role.
[2] The description with the published (c. 1860) print of Schloss Modlau describes the Bibran family as having split off from the Franconia Bibras five hundred years ago.
[4] The son-in-law Ernst Heinrich von Kölichen, who had incorporated the Bibran-Modlau name and coat of arms died (1832) with a daughter, Agnes, but no sons.
