What is "regenbald"

Regenbald (sometimes known as Regenbald of Cirencester) was a priest and royal official in Anglo-Saxon England under King Edward the Confessor. His name suggests that he was not a native Englishman, and perhaps was German or Norman. He first appears in history as a witness to a royal document in 1050, and remained a royal chaplain and clerk throughout the rest of King Edward's reign. Many royal documents give Regenbald the title of "chancellor" but whether this means that he acted in a manner similar to the later Lord Chancellor is unclear, as some of the documents may be forgeries or have been tampered with. Whatever Regenbald's actual title, King Edward rewarded him with lands and also granted him the status, but not the actual office, of bishop. Regenbald continued to serve the English kings after the Norman Conquest of England, although whether he served King Harold II of England is unclear. His date of death is unknown, but it was probably during the reign of either King William I or William II. After his death, some of his lands became part of the endowment of Cirencester Abbey in 1133.
