Ulmen

The Ulmen family holds Ulmen in the volcanic Eifel between Cochem and Daun.

Heinrich of Ulmen, about 25 in 1200, will follow Boniface of Montferrat on the Fourth Crusade, reach Venice in 1202 and Constantinople in 1203-1204, and bring home in 1208 the True Cross reliquary (the Limburg Staurothek) meant for Philip of Swabia, who was murdered before he could receive it. The family holds vineyards at Sankt Aldegund on the Moselle.
