HERBERT. An ancient personal name. The noble Herberts descend from Herbert, Count of Yermandois, who came hither with the Conqueror, and was chamberlain to William Rufus. B.L.G. Collins says : " the genealogists deduce the family from Herbert, a natural son of King Henry I., but I think it more evident that Henry Fitz-Herbert, chamberlain to the said king, was ancestor to all of the name of Herbert."
