The English branch of the family of Byron came in with William the Conqueror; and from that era they have continued to be reckoned among the eminent families of the kingdom, under the names of Buron and Biron. It was not until the reign of Henry II. that they began to call themselves Byron, or de Byron. Although for upwards of seven hundred years distinguished for the extent of their possessions, it docs not appear, that, before the time of Charles I., they ranked very highly among the heroic families of the kingdom.
