The House of Alvensleben[1] is an ancient, Low German (niederdeutsch) noble family from the Altmark region, whose earliest known member, Wichard de Alvensleve, is first mentioned in 1163 as a ministerialis of the Bishopric of Halberstadt. The family name derives from Alvensleben Castle (today Bebertal, district of Börde in Saxony-Anhalt). They are one of the oldest extant German aristocratic families.
