Waldgrave
The first Waldgraves or Wildgraves descended from a division of the House of the Counts of Nahegau in the year 1113.
When the Nahegau split into two parts in 1113, the counts of the two parts, belonging to the House of Salm, called themselves Wildgraves and Raugraves, respectively. They were named after the geographic properties of their territories: Wildgrave after Wald, and Raugrave after the rough terrain.
