The House of Cramm (originally also von Kram, von Cramme or von Crammen) is a noted German noble family of the Uradel and one of the oldest noble houses of Lower Saxony.^[1]

According to a source from 1774, the family came to the area of the bishopric of Hildesheim around 815 with the Carolingian Emperor Louis I and was granted estates there by him.^[2] However, the family is first verifiably documented in 1150 with Dietrich von Cramme. The Cramms were a wealthy knightly family and respected feudatories of the ecclesiastical and secular rulers of the region. From a very early start in their history, the family held high positions at their respective courts. From 1250 on they were the hereditary chamberlains of the Duchy of Brunswick-Lüneburg and from 1294 to 1589 the hereditary cup-bearers of the Prince-Bishopric of Hildesheim. In later centuries family members served the House of Welf as generals, chamberlains and ministers. They held the title of Freiherr (Baron) and owned multiple estates of which the castles of Bodenburg, Brüggen and Oelber are still in their possession.
