In 1778 and in 1779 the Older Line of Irmelshausen acquired the Würzburg fief there. Also in 1779, half of Breuberg was acquired. (The other half was acquired in 1850.) Breuberg appears to be located at or right next to Welkershausen. The Walldorf holdings were reportedly lost in 1946 with land reform under Soviet occupation. As a condition of the reunification of Germany in the late 1980s, the Soviets insisted that land taken by the Russians (as opposed by the East Germans a bit later) not be returned to the former owners.
